It is time to once again look at all things efficiency in front of goal as I have analysed the data from all the action during last weekend’s Premier League fixtures. Don’t be confused by the article title, I feel going forward that it is better to give them individual titles so that they stand out better and therefore should also be Google friendly. Now when we focus on the English top flight the bulk of the attention goes to Manchester City and you would have to say rightly so.

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 13 weeks while also working out the amount of total shots taken

Now let’s take a look at how the 20 Premier League clubs in order of shot efficiency

As always it looks neater in graph form, so as if by magic here is the Premier League shot efficiency graph after 13 weeks of the season

City

Once again Manchester City stay top the charts with a shot efficiency ratio of just 5.2 shots per goal, they are 1.5 shots clear of crosstown rivals Manchester United. While the top three places in the Premier League also fill the top three in this particular chart.

Swansea have become the lowest scoring team in the Premier League and they are now the second least efficient team in the division as they now require 16 shots per goal, while Southampton’s four goal blitz against Everton has done them the world of good as they are now ranked 17th in terms of ruthlessness in front of goal.

As promised though here is a graph depicting the difference in shot efficiency from club to club, I’ll leave the ranking as above so you can get a clearer idea of the change from Week 12 to Week 13

City

But it’s this chart that gives a greater detail as to how a team performs from week to week, for example Manchester City’s efficiency ratio is unchanged from last week while the same can be said for Leicester who are the fourth ranked team in the list.

The minus figures here indicate an improvement while the positive figures include a worsening off, so as you can see the big winners this week are Southampton and Crystal Palace but you do need to keep in mind that they were starting from such a high base so it was always likely that once they start scoring more then there large shots to goals rating was always going top come down.

Tottenham were once again frustrated at the weekend and they saw their ratio increase by 0.7 shots, they now need 11 chances before scoring. Whether they need to be congratulated for creating so many or castigated for the profligacy is something that can be argued. Again should a team be punished by this metric for being such an attacking team.

Let’s now take a look at the Premier League if it was ranked by shots this season

Team GF Total Shots
Liverpool 25 237
Tottenham 21 230
Manchester City 42 220
Arsenal 23 216
Manchester United 28 189
Southampton 13 179
Chelsea 24 173
Newcastle United 11 169
Crystal Palace 8 163
Watford 22 160
Stoke 16 146
Everton 13 138
West Ham 12 134
Burnley 12 129
Bournemouth 11 126
Leicester 17 124
Huddersfield 9 114
Brighton 13 112
Swansea 7 112
West Bromwich Albion 10 108

It’s Liverpool who top this list with 237 shots this season, seven clear of Tottenham while league leaders Manchester City find themselves third in list. Mauricio Pochettino will no doubt be shaking his head as to just how his side drew against a team that have only 108 efforts and the lowest in the division. That of course being West Brom.

For all the chances that Liverpool create the criticism is perhaps that they do not score enough and are not as ruthless, you only have to compare them to Manchester City. 17 more shots by Liverpool but 17 less goals this season, then again you could point to Pep Guardiola’s men raising the bar to phenomenal levels.

There’s also the obvious correlation between Swansea being the lowest scorers in the league and also creating so few chances, they along with Brighton have created the second fewest chances in the division but while Brighton find themselves as the 6th highest ranked team, Swansea sit in 19th in terms of efficiency in front of goal.

Let’s now take a look at how the league table compares with the shot efficiency ranking

City

Once again it is Leicester and Stoke as the big winners but last week it was Claude Puel’s men out in front and this time around it is the two of them with the biggest positive variance – they perform eight places better off in terms of shot efficiency than compared to their league placing.

Five teams have no change and it is quite interesting here that the top three and the bottom two teams in the Premier League have an identical match, I don’t think we’ve seen such a neat connection between the two metrics this season.

Also it’s interesting to see the biggest winners are teams all in the bottom half of the table, this would indicate to me that it is their defence which is letting them down as you only need to look in the goals against column of any of the top five ‘winners’ in this list for that point to be proven.

While Tottenham have the biggest negative variance this week, this is the case for the second week in a row. This can be explained by the fact that although they are failing to win they are still creating many chances but this is not then being converted into goals.

The three parameters are split as such:

7 Positive
5 Neutral
8 Negative

Let’s see how the rankings have changed week on week as we find out who are the biggest movers and shakers

City

Surprisingly it is Everton and West Brom who are the big winners by virtue of scoring a goal where the likes of Newcastle, Swansea and Bournemouth all drew blanks. While Southampton have profited two spots this week after beating David Unsworth’s men 4-1.

It’s quite surprising that 10 teams did not move and this includes the likes of Manchester City and Manchester United, actually on closer inspection the top six are unchanged with only Stoke and Arsenal switching places in the whole of top eight.

Bournemouth are the big losers this week as they fell 3 places compared to last week while Tottenham will want to put this week to bed as they slipped a further two places down the rankings.

I think that just about concludes Week 13, as you can see the content is getting longer and longer with each gameweek but that is simply because there is so much data to use and more and more findings every week. I’m going to put some of those findings into separate articles so as to make sure this doesn’t get too long going forward.

I’ll return later in the week with the offering from Week 14 as I analyse what changes would have come about after all the midweek Premier League action.

 

I hope this was of interest to you and if you have any football data work available then please contact me at realfootballmanwordpress@gmail.com as I am always looking to undertake additional projects to the ones I already have. Thanks, Dan.
