He needs 6.3 shoot/game to get 31 goals, while 12 of them is penalty so he actually only get 19 open play goals in serie A all season
The lower shoot per goal number but higher goals it tells the player is more prolific
So if we count his total game in Serie A this season (33 games played)= 33 x 6.3 = 207 shoots to get 19 goals (9.18% conversion ratio)
Lets compare with Immobile (37 games played), 14 penalty = 37 x 3.8 =140 shoots to get 22 goals (15.7% convertion ratio)
Werner this season (34 games played), 3 penalty = 34 x 3.6 =122 shoots to get 25 goals (20.4 convertion ratio)
And even Immobile and Werner still getting pretty high number of assists
As for Messi, his assists number is really high, it means beside he drive the team by his goals, he support the other strikers too
That goal Ronaldo scored against Lyon for example, from 25 meters on his left foot while having something like 15 players stacked in front of him isn't the shot most of the players are willing to take, especially on their weak foot and the conversion rate with that shot cannot be that high. If he never took the shot, wouldn't have never scored the goal either so..I can also say that Immobile for example has way more freedom around him, he doesn't get noticed that much as Ronaldo/Messi for example. That's also one of the reasons you seeing someone banging 20 goals in his first year, then never repeating it again because he gets noticed.
