The top 2 EPL goal scorers, Liverpool's Mohamed Salah and Tottenham's Harry Kane, both took over 110 shots--35 more than anyone else, as shown in this bubble chart. Salah was more efficient than Kane, converting 28% of his shots to goals, compared to Kane's 22%. Salah and Kane also scored significantly more goals than their peers--32 and 30, respectively. The other top scorers all scored 21 or fewer goals.
Leicester City's Jamie Vardy was the most efficient goal scorer, converting 34% of his shots. Manchester City's Raheem Sterling followed with 31%. Kane was the least efficient. Manchester City's Sergio Aguero and Gabriel Jesus and Arsenal's Alexandre Lacazette all converted on about 28% of their shots. Liverpool's Robert Firmino and Manchester United's Romelu Lukaku converted on 25% and 24% respectively.
Aside from Salah and Kane, the other top scorers took between 47 and 74 shots. Aguero took the most shots and scored the most goals among this group. Jesus took the fewest and scored the fewest.
How I Created the Bubble Chart
I found the data for this chart on the BBC Sports site. The site had data for the top scorers on minutes played, shots taken, shots on target, goals scored and assists made for the top scorers. I entered the relevant data for the top 9 scorers into Excel and created formulas for goals scored per minute played and per shot taken. After some experimentation with different statistics, I decided to use shots taken and goals scored as a percentage of shots taken as by x and y variables and goals scored as bubble size. This told a simple story about how many times the player tried to score and how efficient they were per try.
Here are the steps I took to create the chart:
- copy the x, y and bubble size data and team name from the Excel spreadsheet into the PowerPoint bubble chart
- adjust x and y axis minimum, maximum and tick interval to space out the data along the two dimensions
- display player name and goals scored in each bubble, adding " Goals" as a custom suffix to the bubble values
- adjust margins and add axis titles
- hide the reference bubble and show the legend
- adjust the bubble colors using the team's primary color (found at https://teamcolorcodes.com/premier-league-color-codes/) and entered into Mekko Graphics using RGBs
- adjust bubble labels
