English Premier League – Possession with Purpose – Week 2
Two weeks in and Manchester City pretty much throws the gauntlet down against Liverpool and walks away with a dominating win.
Three other teams have also begun the season with six points (Spurs, Swansea, and Chelsea) but do those four teams show the most consistency with purpose in possession, penetration and creation of shots taken that result in goals scored?
And, do those same four teams show the most consistency in preventing their opponents from doing the same thing to them?
What about the early season dogs (QPR, Burnley, Crystal Palace, and Newcastle) – where do they fit?
I’ll try to answer those questions without too much detail given the season is just two weeks old.
So to begin; here’s the Composite PWP (CPWP) Strategic Index after Week 2:
- A quick look at the table sees the top four in the Index as being the top four in the Table – not specifically in order but there it is.
- In looking at the bottom end of the Table the bottom four teams in the Index match exactly the bottom four in the Table.
- I doubt very much the level of accuracy will match the League Table that well throughout the year.
- Of note is that Arsenal, Hull and Aston Villa are next up in the Table but Villa seems to drift down a bit in the CPWP; perhaps the APWP or DPWP might explain that drift compared to Arsenal or Hull City?
- As a reminder – the End State of the Index is to provide an objective view of team performance indicators that don’t include Points in the League Table – in other words it’s a collection of data points, that when combined, can provide value in what team activities are occurring that are directly supporting results on the pitch – sometimes results on the pitch don’t match points earned…
- In leveraging this Index last year in the MLS it was very accurate in reflecting why certain Head Coaches may have been sacked – in a League like the EPL (where everything is expensive) perhaps this Index might have even more value to ownership?
- Movement in the Index – in the MLS, this last year, I have seen teams move up as many as 12 places and down as many as 11 places – after the 4th week – so the Index is not likely to stay constant – there will be changes.
I do not quantify Index outputs specific to individual player acquisition or performance – there is no intent to do this. It’s my belief, good or bad, that even with individual star performances a team is a team is a team – you win as a team and you lose as a team… but this Index isn’t intended to stop others from doing that.
I leave that individual analyses for others who are far better at digging into the weeds than I – for the EPL I’d imagine many folks gravitate to @statsbomb or other @SBNation sites – I respect their individual analyses as I hope they respect my team analyses.
Whether the consistency of value shows itself in assessing team performance in the EPL like it has in Major League Soccer I have no idea – we will follow that journey, in public, together…
Now for Attacking PWP (APWP):
- In recalling Villa’s drift (it is still early) perhaps it’s an early indication that Villa are playing slightly more direct (given past indications analyzing Major League Soccer) – or with a greater lean towards counter-attacking and quick transition?
- In taking a quick look at their average volume of passes per game (305) compared to the rest of the EPL (456) it would seem to indicate Villa are playing more direct football.
- The team with the highest APWP while falling below the average number of passes attempted, per game, is Leicester City; they average 308 passes per game compared to the 456 average of EPL. For me that’s an early indicator that they are making the best use of a direct attacking scheme – others may have a different view?
- The team with the lowest APWP while showing higher than the average number of passes attempted, ~(500 per game), is Stoke City – that might indicate the Potters are looking to possess the ball more with the intent to possess it as opposed to penetrating with it. Folks who follow Stoke a bit closer might be able to add to that as I’ve yet to see them play this year.
- In terms of early form, relative to the six team performance indicators, Chelsea are tops with Everton, Arsenal, and Man City close behind.
- With respect to bottom feeders QPR are bottom in CPWP and bottom in APWP as well; most figured they’d be early favorites for relegation – the PWP Indices seem to lean that way already as well…
- Perhaps the early surprise in APWP is Newcastle? Not sure about that one – last time I lived in England Alan Shearer was their striker and probably the best one in the country at that time… others will no better about what Alan Pardew is up to…
Next up Defending PWP (DPWP):
- Leaders here include Spurs, Man City, Swansea and Newcastle – is this an early indicator that Newcastle has experienced bad luck already? Not sure but three of the bottom dwellers here are three of the four bottom dwellers in CPWP.
- Although not real clear here it might be easy to forget that Arsenal had a blindingly great first game and then eked out a draw against Everton in the last ten minutes; in considering that this data still just represents two games…
- Recall Stoke City – and the potential view that they might be possessing the ball with an intent to possess more-so than penetrate – even with just 1 point in the League Table their DPWP exceeds West Ham, Liverpool, and others who are further up the table.
- Man City showed great nous last year in winning the League and it reaffirmed for many of us the importance of defending – Liverpool were close last year given an awesome attack – players have changed but it’s likely the system/approach has not varied that much. And after two games Liverpool are embedded firmly in the middle of the DPWP pack.
- Can they push higher up the DPWP? And if so, will that climb in the DPWP Index match a climb in the League Table; or vice versa?
Far too early to look for trends but these first few weeks will provide a baseline for future trends.
As noted in my most recent articles on Possession – the more accurate soundbite on whether or not a team is more likely to win has more relevance with respect to Passing Accuracy (>77% in MLS usually means a team is more likely to win) and not Possession.
The margin of winning and losing in MLS is far to muddied when looking at Possession – so as the EPL season continues I will also make it a point to study what ‘soundbite’ has more relevance; Passing Accuracy or Possession.

EPL – Charting progress after 12 Weeks
It’s been a couple of weeks since I checked in with the English Premier League so here’s a quick fly-by on who’s leading the league in team performance, exclusive of the League Table.
That’s not to say I’ll ignore the League Table – in summary here’s the top six and the bottom six respectively:
- Chelsea, 32 Points
- Southampton, 26 Points
- Man City, 24 Points
- Man United, 19 Points
- Newcastle, 19 Points
- West Ham, 18 Points
- Swansea City, 18 Points
- QPR, 8 Points
- Burnley, 10 Points
- Leicester City, 10 Points
- Hull City, 11 Points
- Aston Villa, 12 Points
- Crystal Palace, 12 Points
Now for my Composite PWP Strategic Index:
In comparing the top six in the League Table to the top six in my Index Chelsea, Southampton, Man City, Swansea City, and Man United are all in.
Everton and Arsenal continue to ride high in this Index – whether that continues or not is yet to be seen.
The question I have is this — is it the results that end up catching up with the team performances, or is it the team performances that end up catching up with the results?
In Major League Soccer the team performances usually seemed to lag when compared to the results – if that is the case here then I’d expect Everton and Arsenal to drop further in the League Table if there are systemtic attacking or defending issues.
On the other hand – like Newcastle – the team performance lags the results and both Arsenal and Everton should begin winning more games…. more to follow…
As for West Ham, we already know they will be on the shorter end given their more direct style of play but the surprise mover is Newcastle; especially since in Week 5, where they were 6th worst in the Composite Index (see below).
Clearly team performance has improved considerably – not only in results but in team performance; that’s a good thing when considering the viability of the Index. Besides, I don’t read too often anymore where Alan Pardew’s head coaching status is in question.
As for the bottom six; well we have QPR bottom in both, with Crystal Palace, Aston Villa, Leicester City, and Burnley all in; the odd one out is Hull City.
Might that mean Hull City are more on the ‘lucky’ end of results than their team performance indicates?
I’m not sure but when we peel back APWP and DPWP we might be able to see where the general weaknesses and strengths are that help Hull City stay outside the relegation zone as the season continues.
Attacking PWP Strategic Index:
In considering the top six teams in the League Table it appears to me that the Attacking team performances for Chelsea, Man City, Southampton, Man United, and West Ham are a strength more than a weakness.
Defending PWP Strategic Index:
Given that the DPWP for Newcastle is stronger than the APWP, I’d offer that it’s the Defending team performance that is helping to push Newcastle near top of the table.
Not to be missed though is that Southampton, Man City, Chelsea, and Man United are also all in the top six.
The lone wolf, in defending, is West Ham. But we already know from previous analyses that Sam Allardyce likes to play more counter-attacking football – so it shouldn’t be a surprise to see them in or around the middle.
It’s when their DPWP starts dipping below the halfway point that those forever blowing bubbles should be considered.
Southampton continues to find success; granted their 1-1 draw with Aston Villa was probably disappointing, but with that 80th minute goal they were able to scratch out at least one point against Villa.
The surprising result to me, and probably most everyone else, was the 3-1 pasting Liverpool took against Crystal Palace.
The most amazing statistics for me out of that game was seeing Palace offer up 15 shots taken with just 71 completed passes in the Liverpool Defending Final Third – and of those – 15 shots were taken with five of them were on goal!
I guess that shouldn’t be surprising to the average stats person given that winning teams in the EPL average just over five shots on goal with at least two goals scored. In this case Palace got three goals.
On the other hand, with 519 passes offered, 460 which were complete, and 96 of those were completed in the Palace Defending Final Third, you’da thought Liverpool would end up with more shots taken and more shots on goal.
They didn’t. What is even worse is they had five of those 12 shots come from prime locations and only one ended up on goal!
For me, this means reinforces two things:
- Time and open space has great value when considering the quality of shots taken, regardless of location, and
- Liverpool have yet to find a striker who can take shots and put them on goal. I would expect Liverpool to be in the market to buy a top striker as soon as possible!
If you’re a betting person; here’s the latest CPWP Predictability Index. This does not yet to into account the differences between team performance on the road versus at home.
It should be noted that teams playing at home, in the EPL, have taken 182 points – versus teams playing on the road have taken 143 points.
In terms of a ‘rough estimate’ that means 56% of all points earned are earned at home games.
Not much of an edge – but – if you’re a team like Crystal Palace, playing a team like Liverpool, who is clearly shaken – and not stirred – there will always be the chance of an upset!

English Premier League Week 3 – Chelsea blow past Everton but it’s not all about Chelsea this week…
Perhaps a few shockers this past weekend – Queens Park Rangers defeating Sunderland 1-nil and Burnley (only?) drawing with Man United nil-nil certainly are intriguing, and from a pure entertainment standpoint the Chelsea game had it all.
But soccer isn’t about one specific week in League competition – it’s about the consistency of purpose in performing week in and week out.
So for the first three weeks my two teams operating at (unexpected) peak performance are Swansea City and Aston Villa.
Now I’m sure others feel or think Chelsea deserve some credit and they do – but at this stage they’re boring as I’d have expected them to do well.
And as for Manchester United – well… I’ll give them a look a bit later during this 2 week break.
For now though a special look at Swansea City and Aston Villa; wrapped up within my Possession with Purpose Strategic Index analysis after Week 3.
With that here’s the tale of the tape in Composite Possession with Purpose after Week three:
The early season form for Swansea City sees them completing ~85% of all their passes with a mid-table ranking, in Final Third completions, at ~67%.
The most telling difference between Swansea and other teams, early on, is their superb ability in putting shots on goal, per shots taken, (55.56% – leading the EPL) and a healthy 39.29% of goals scored, per shot on goal.
And while the location of those shots might have some value – I expect the space and time the strikers had was telling; in checking shot location for Swansea City it appears 50% of their shots originate from outside the 18 yard box with 2 of them scoring; while 4 of their 15 inside the box have resulted in goals.
What’s amazing here is that both Swansea and QPR lead the league in Shots Taken per possession-penetration into the Final Third.
Swansea averages 20.88% shots taken per penetrating-possession – while QPR averages 21.40% (leading the EPL).
Where QPR falters, big time, is they’ve only managed to put 20% of those shots on goal and a measly 8% of those shots on goal have resulted in a goal…
Again, shot location might have value but I’d expect their shot location is okay – where they falter is (perhaps?) more about lack of patience and clear space in order to take quality shots…
A quick check indicates that 24 shots from QPR have come from within the 18 yard box – while 21 shots have come from outside the 18 yard box… seems to reinforce my time and space theory as opposed to strictly looking at shot location… others may have a different view?
Can you say QPR need to buy some strikers?
I would – but perhaps even more important is it appears to me that QPR also need to buy one or two midfielders that have more patience in setting up more shots for their teammates in open space.
Just another example here of why I’d like to see those two new statistics in soccer – Open Pass and Open Shot…
And yes, Swansea have only faced Burnley, Man United, and West Bromich Albion.
At this stage that might not be saying a whole lot but a win is a win is a win – and Swansea have three of them!.
A mid-season win has no more, or less value, than an early season win. So all those second guessing the early season form should recognize nine points is far better than three points; or like Man United, one point!
As for other team performances – it was disappointing to see Man City couldn’t put one past Stoke City this weekend.
They had plenty of possession and penetration, but alas, as Swansea and Chelsea so deftly point out, the full run of the game means you need accuracy in shots taken just as much as accuracy in passing, both inside and outside the Final Third.
Of course, having a player who can dribble-sprint 60 yards, dodge past three players, and meg the keeper, can really help a team – well done Stoke City.
So how do the teams compare in the Attacking PWP Index?
Chelsea – surprised?
Probably not… What a thrilling match that was; nine goals with six of them by Chelsea.
And we shouldn’t ignore Liverpool and that three goal burst against Spurs… a shocker? (perhaps?) but we’ll know if that’s a real shocker sometime later this season.
As for Everton, scoring three goals themselves, don’t pay a penalty in APWP for the lack of scoring goals – where their drop in overall performance comes is in viewing the DPWP Index – here:
Last week Everton were 5th worst in DPWP – rightly so given they had already given up two goals to Arsenal and two goals to Leicester City.
All told that’s 10 goals against in just three games… wow… Martinez is going to have to make some changes (big money changes) if that goals-against rot continues… even now I’d expect them to work very hard during this early season break to fix their defense….
So who’s a great example of how an effective Defense keeps a team shining, even when the attack isn’t the best?
While only three weeks have been played my shining example is Aston Villa.
They are ranked 4th worst in team attacking performance but when it comes to team defense… they’re ranked 4th best. A great example of where strong defense gets you points – they have seven at this stage.
So how does that 4th best translate to success on the pitch?
Opponents are completing ~64% of their passes in the Villa Final Third – 7th lowest in the EPL. Of note is that opponents are possessing the ball better than 60% of the time.
For me that means Villa yield possession, up high, and play slightly deeper and tighter in their own half.
That compact approach, in their defending half/third, sees the opponent completing just under 20% of their total possession in the Villa Final Third.
In other words, even when the opponent has the ball, 80% of that possession is outside the defending third —> (of no major consequence)…
And, even more impressive, is that when the opponent does penetrate – only ~12% of that penetrating possession results in an opponent shot taken. And of that 12% only 29% of those shots taken end up as shots on goal.
Remember those stats from Swansea and QPR and how low QPR was in finishing (8%).
Well, as a team, opponents of Villa have just 11% of their shots on goal resulting in a goal scored against. That is 2nd lowest (best) in the EPL and only Swansea is lower – permitting just 6.67% of their opponents shots on goal scoring a goal.
Clearly these two teams are performing at peak compared to others.
So for a quick comparison – Villa yield possession at 60% (on average), while Swansea do not yield possession; their opponents average 49.19% possession.
So from a defending tactical view Swansea’s game style is not the same as Villa’s.
Swansea appears (data wise) to play a bit higher and yield penetration a bit more.
Opponents penetrate 23.11% of the time they possess the ball and take more shots against than Villa’s opponents who average 15.11%.
So an apparent tighter (man-marking) defensive scheme sees Swansea opponents having fewer shots on goal per shot taken; 19.13% versus Aston Villa at 28.79%.
Bottom line here is the contrast in defending styles can be noted, tracked, and measured without looking at tackles, interceptions, clearances, etc…
In other words it helps scratch that itch of measuring what doesn’t happen on the pitch as opposed to what does happen.
My earlier views on that can be read in this article published earlier.
Still early so no more diagrams – over the next couple of days, after putting together my Bundesliga and La Liga Weekly recaps I’ll go back and pick out some thoughts about Manchester United after three weeks, what weakness and strengths the data behind the Indices might offer.
All for now.
