Why not? This is not just some robotic role player moving in a specific rigid system. Is a case of a insanely quick, skillfull, brilliant dribbler with strong shot getting maximum freedom to express himself as naturally as he can. Yeah Citys set up is super ideal for players like him, its the opposite too, he is super ideal for why that set up even works.
He is really young still but he has the natural end product of the top players already in final third. Yeah he can be bit rash, undisciplined and over dribble at times, as he did in first few games German NT. And he plays with the best of the best in City in individual level, but he was genuinely top few reasons why that attack was fast insane and deadly. Individually 1 on 1, he was the best pure player in that team at going at defenders. He opened up so much space at will. Majority of Sterlings goals was him just bulldozing past players and serving him infront of goal.
