Time to once again discuss all things shot efficiency as we return to the Premier League for the third article in this particular series, with each week that passes we will have more and more data and ultimately that will allow us to build even more correlations and conclusions as the season progresses.
You can take at the previous week’s data to compare and contrast but going forward I shall be adding in some charts to track the ongoing process and with that in mind let’s take a look at the data after Week 12 of the Premier League season.
Once again thanks to whoscored.com for all the necessary data.
Here is the Premier League league table after 12 weeks while also working out the amount of total shots taken
|R||Team||Shots pg||Games Played||Total Shots|
|17||West Bromwich Albion||8.6||12||103|
Now let’s see how that table differs when we ranked the 20 clubs in terms of shot efficiency
|Team||GF||Total Shots||Shot Efficency|
|West Bromwich Albion||9||103||11.5|
Let’s see what does in terms of showing the data in graph form
As you can see Manchester City once again top the list with their efficiency rating going out to 5.1 from 5.2 but they are still more than a shot clear than that of their nearest and crosstown rivals Manchester United who are currently on an average of 6.4 shots per goal.
Chelsea have moved into the top three which means we have the scenario where the the top three in the Premier League are also the top three in this chart while Leicester once again seem to be over performing requiring just seven shots per goal.
What is also interesting is if we rank the 20 clubs in order of shots this season
|West Bromwich Albion||9||103|
It is actually Liverpool that have had the most shots in the Premier League this season but they are only the ninth most efficient team in the division. Jurgen Klopp’s men actually require an average of 9.2 shots per goal something that sees them sit ninth in the table. So for all their attacking endeavour they could however be a far more ruthless.
Then same could also be said for Tottenham who have the third most shots in the Premier League, just one less than Manchester City but what is the most startling fact is that they have scored fifty percent less goals than that of the league leaders. This sees them become just the 11th most efficient team in the division.
At least Crystal Palace’s plight has improved slightly they may still be bottom of the table both on the pitch and in terms of shot efficiency but at least their shots to goal ratio has moved to a slightly more respectable 25.6 efforts before breaching the opposition’s net.
Now let’s take a look take a look at the variance graph between league placing and shot efficiency
As you can see it is once again Leicester who top the charts in terms of variance. They may be 12th in the league but they are the fourth most efficient team in the league so they are over performing in front of goal but it is also fair to say that their defence is massively letting them down.
Stoke are the second highest team in terms of variance as they sit 15th in the Premier League but just 8th in this particular ranking. This can be explained by the fact that Leicester and Stoke are the two teams that have scored the most goals out of all the teams in the bottom half of the table.
Spare a thought for Tottenham though as they have the biggest disparity between their league placing and shot efficiency ranking. They currently are 4th in the table but are only the 11th most efficient team in the division therefore there is still a hint of under performance here.
Let’s take a look at the make up of the three parameters
It’s interesting that three of the top six and even by extension four of the top seven have a negative variance, maybe that can be argued by the fact the bigger clubs create more while Burnley are still something of an anomaly this season they continue to defy the pundits.
I’ve also now added a graph where we can track the movement week on week so let’s see who the biggest movers and shakers are in Week 12
There is no doubting who the biggest winners where last week, that of course being Bournemouth who thanks to their 4-0 win over Huddersfield they moved from 18th to 12th in the efficiency ranking while bringing their shots to goal ratio down to just 10.7
While Chelsea and Everton also profited this week with a rise of two places up the table. The only other team to move up the ladder this week was Sean Dyche’s Burnley. Again not a good week for Tottenham as after their North London derby defeat they slipped down a further spot.
I think that just about concludes Week 12, other ideas for charts going forward will be the difference in shot efficiency week on week to see just how much it has moved in either direction and we can also look at the variance between shot efficiency and the ranking in terms of shots per club. That is something to think about going forward. I told you this would get longer and longer as the weeks progress!
I hope this was of interest to you and if you have any football data work available then please contact me at firstname.lastname@example.org as I am always looking to undertake additional projects to the ones I already have. Thanks, Dan.
