Country: England
Hence my reservations to compare them all.He's already on 5 PL goals this season, with basically half the fixtures left to play, it's very conceivable he hits double figures, and he's getting those numbers in a largely broken team.
Saka for all his minutes - numbers wise he isn't as impressive as the others. However, we all know as fans the responsibility he has and the state of the team which goes against him. He kinda carries us where I am not sure if Foden/Greenwood/Sancho could.
In my personal opinion, you get more bang for your buck with Foden and Sancho - but they are in much better teams/much better coaches/much better everything, I find it really hard to tell who's best.
Out of all of them, I back Saka the most to still be around at the top of the game 5-10 years from now. His mental fortitude is what impresses me the most about him.
