No idea, maybe xG to show how good they are to get into goal scoring position but then again it depends on how the team is set up, how good the supporting players are and all that.
If we take xG and compare to some of the greats and some of our own players:
Erling Haaland in the BL since jan 2020:
xG90 = 0,78
xG total = 22,65 goals - scored 30 goals
goals/90 = 1,04
Has outscored his xG90 with 32,5%
Average shots/90 = 3,18
Cristiano Ronaldo in LaLiga and Serie A since summer 2014:
xG90 = 0,96
xG total = 198,01 goals - scored 205 goals
goals/90 = 1,00
Has outscored his xG90 with 3,5%
Average shots/90 = 6,24
Lionel Messi in LaLiga since summer 2014:
xG90 = 0,85
xG total = 184,12 goals - scored 220 goals
goals/90 = 1,02
Has outscored his xG90 with 19,5%
Average shots/90 = 5,45
Robert Lewandowski in BL for Bayern Munchen:
xG90 = 0,97
xG total = 189,64 goals - scored 190
goals/90 = 0,97
Has scored on par with his xG
Average shots/90 = 4,57
Mbappe in Ligue 1:
xG90 = 0,81
xG total = 86,09 - scored 98
goals/90 = 0,93

Average shots/90 = 3,96
Lukaku for Manchester United in the PL:
xG90 = 0,53
xG total = 28,58 goals - scored 28
goals/90 = 0,51
A tiny bit below his xG
Average shots/90 = 2,52
Cavani for Manchester United in the PL:
xG90 = 0,68
xG total = 6,29 goals - scored 6
goals/90 = 0,65
A tiny bit below his xG
Average shots/90 = 2,59
Martial as a CF for Manchester United in the PL:
xG90 = 0,44
xG total = 31,94 goals - scored 32
goals/90 = 0,44
On par with his xG
Average shots/90 = 2,4
From this we can read:
- Our strikers has been decent finishers, but has lacked a bit of service or has not created too many chances for themselves.
- Ronaldo and Lewa has had excellent service and been great at creating chances for himself while his finishing has been decent.
- Messi's finishing has been excellent, while also getting great service and creating a lot of chances for himself.
- Mbappe is great at finishing and has had decent service while also creating some chances for himself.
- Haaland looks like the superior finisher by some distance of the lot, despite getting limited service and not creating too many chances for himself still scores the most goals per 90.
If you put into context that Ronaldo, Messi, Lewa and Mbappe has played for very dominant teams in their leagues and have been the focal points of these teams ( - Mbappe to a certain degree) as well, it makes what Haaland is doing even more outstanding.
There is of course not much context behind these numbers either, but no matter how you twist and turn every statistic out there, this 20 year old Norwegian stands out.
