Yeah I never doubted his stats. Or his contributionI think it was Sterling's awkward style of play which always made his misses look worse.
At the end of the day he was the best goal scoring wide player we've ever had and levels above anyone we have right now with only Foden starting to show he can get to that level. Even Foden isn't yet at the 31 goal season peak that Sterling had.
I look at someone like Grealish and he fluffs just as many chances and also doesn't get into anywhere near the amount of goal scoring positions either but no one talks about him not being about to finish because it's not a 'thing'.
Sometimes you have to look at what else they bring to the table and that can be more than enough to outweigh the weaknesses and Sterling's goal contribution for City far outweighed the fact he wasn't finishing all his chances like a seasoned center forward.
But Grealish and Foden are much more talented than him. I bet most footballers (pro and grassroots) would tell you the same thing. You allude to the same with his 'awkward style of play' i.e. not a natural footballer who has an affinity with a ball.
Grealish actually gets slagged off a lot on here because of his goal and assist contribution, or lack thereof. But based on the 'eye test' ie watching him - he's a better footballer than Sterling no doubt. Vastly superior first touch, far more comfortable on the ball, better passer. When Grealish is on it, he facilitates other players and makes them look better in a way Sterling never could or did. But he's not a stats fiend so he doesn't appeal to those types.
Ultimately Sterling was finished before he was age 28. Pep made him look a better player than he was in my opinion. Now Pep does that with plenty of players but it was really pronounced with Sterling for me.
And I would suggest how poor he's been at Chelsea (with the caveat that they're a disgrace of a club) would back me up. He won't EVER be back competing for top honours.
