Stat Analysis | Who is the Best Goalscorer in the Premier League

With the race for the golden boot tighter than ever, I decided to crunch some numbers to see who is the best goalscorer in the Premier League. In this post I’ll outline the stats I used, who is best in each category of my analysis and then try to predict what the final goals tally will look like. I took the 13 top scoring players in the PL this season as the sample. First let’s look at a number of stats comparing players performance this season to last.

Salah

 

Raw Data

Shot Success

Shot Success

Shot Success is the ratio of shots to goals. We can see that Aubameyang is far ahead here with ~32%. Glenn Murray isn’t far behind, along with Raheem Sterling and Anthony Martial. What we’re seeing here is Aubameyang and Murray being clinical with their shots. Whilst Sterling and Martial aren’t shooting as often, they’re scoring a good percentage of their shots. Richarlison missed a lot of shots last season which brings his overall down under 10%.

Winner: Pierre-Emerick Aubameyang


Big Chance Conversion

Big Chance Conversion Rate

Big Chance Conversion is a measure of how many ‘big chances’ (according to PL.com) each player has scored/missed. Here we can see that Aleksandar Mitrovic has been the most reliable over the last two PL seasons with 70% of his Big Chances scored. Murray has scored all of his Big Chances this season, and is only slightly behind. Kane and Salah have missed a lot more Big Chances this season, which could account for their lack of goals so far.

Winner: Aleksandar Mitrovic


Minutes Per Goal

Mins Per Goal

Goals per minute can be a good method of measuring a forwards goal return. Richarlison and Sigurdsson are actually off the scale at over 500 mins per goal last season. The best in terms of GPM are Aguero, Aubameyang, Harry Kane and Mo Salah, all averaging one goal every 100 or so minutes. It is interesting to see Eden Hazard doing much better this season under Sarri, showing he really is getting forward more.

Winner: Sergio Aguero


Penalty Area Shot Conversion

Next I looked at the best shot to goal ratio inside the penalty area. As you’d expect Aubameyang came out on top again, followed by Murray and Sterling. It’s interesting to see Sterling this high up, it really shows he is getting into the box more and creating chances for himself. Martial has started brilliant this season in this regard, but looking at his return last season it isn’t likely to last.

Winner: Pierre-Emerick Aubameyang


Team Contribution

Finally I looked at each player’s team contribution and how important they were to their respective clubs. As you’d imagine, the stats suggest that Harry Kane and Glenn Murray are the most important players for their clubs, scoring over 35% of their goals over the past 2 seasons. Mo Salah is also very influential at Liverpool.

Winner: Harry Kane


Manipulating the Data

The next step was to begin data manipulation in order to try and predict the number of goals each player would score over the course of the season. I first kept it very simple. Taking each players goals per minute so far this season, and assuming they played every remaining minute of this season, what would their goal return be. The table looked like this:

Player Predicted Goals (GPM 18/19)
Pierre-Emerick Aubameyang 31
Raheem Sterling 26
Sergio Agüero 26
Anthony Martial 24
Eden Hazard 23
Glenn Murray 22
Harry Kane 22
Richarlison 20
Mohamed Salah 20
Callum Wilson 19
Aleksandar Mitrovic 19
Sadio Mane 17
Gylfi Sigurdsson 17

However, this is a very crude estimation, which only takes into account this seasons form. For instance, I would be very surprised to see Martial on 24 goals and Murray on 22 at the end of the season, compared with Salah’s 20. To achieve a more realistic result, I combined data from this season and last.

Player Predicted Goals (GPM Overall)
Pierre-Emerick Aubameyang 31
Sergio Agüero 29
Mohamed Salah 27
Harry Kane 27
Raheem Sterling 24
Anthony Martial 20
Aleksandar Mitrovic 20
Glenn Murray 20
Eden Hazard 19
Callum Wilson 17
Sadio Mane 16
Richarlison 12
Gylfi Sigurdsson 12

This was starting to look a bit more realistic. Next I looked at big chances. Players like Kane and Salah had missed a lot more big chances this season than last. I reasoned that this should balance out over the course of the season, so I took their average Big Chance Conversion rate over the last two seasons and applied it to the remaining games. This produced this result.

Player Predicted Goals (Big Chances)
Mohamed Salah 32
Harry Kane 31
Sergio Agüero 28
Pierre-Emerick Aubameyang 27
Callum Wilson 22
Raheem Sterling 20
Sadio Mane 15
Eden Hazard 14
Aleksandar Mitrovic 14
Anthony Martial 13
Glenn Murray 13
Gylfi Sigurdsson 12
Richarlison 7

You can see that this drastically improved Salah and Kane’s figures, whilst reducing Aubameyang and Sterling’s. This is due to the fact that this is influenced much more by last season’s numbers.

Finally I looked at the number of shots each player had in the box and their chance of converting, again for the last two seasons. Then modelled a prediction on the remainder of the season.

Player Predicted Goals (Shots In Box)
Pierre-Emerick Aubameyang 31
Sergio Agüero 29
Mohamed Salah 27
Harry Kane 27
Raheem Sterling 24
Anthony Martial 20
Aleksandar Mitrovic 20
Glenn Murray 20
Eden Hazard 19
Callum Wilson 17
Sadio Mane 16
Richarlison 12
Gylfi Sigurdsson 12

Again it was Aubameyang on top, followed closely by Aguero. Kane and Salah just don’t seem to be scoring as many chances as they did last season, whilst Aguero and Aubameyang have picked up where they left off last year.

To conclude, I calculated some averages to produce a final table of what I predict the top goalscorer table will look like at the end of the season.

Player Mean Median
Pierre-Emerick Aubameyang 30 31
Sergio Agüero 28 29
Mohamed Salah 27 27
Harry Kane 27 27
Raheem Sterling 24 24
Anthony Martial 19 20
Glenn Murray 19 20
Aleksandar Mitrovic 18 19
Eden Hazard 19 19
Callum Wilson 19 18
Sadio Mane 16 16
Richarlison 13 12
Gylfi Sigurdsson 13 12

So, there you have it. According to the stats, Pierre-Emerick Aubameyang will be top scorer at the end of the season. I must stress this is not based on the fixture list nor does it take into account injuries or European fixtures that might mean players are rested. But the statistics are solid (as of Gameweek 14), and it’ll be interesting to see if it’s close come the end of the season.

If you were interested in this post and want to see more statistical pieces like this, let us know. I was thinking of writing a piece about other positions in the future, and possibly looking into any questions you have. All stats were taken from WhoScored and The Premier League.
