Pavel Nedvěd! Never spoken about like Zidane Scholes Vieira Keane Xavi Iniesta Gerrard Lampard are. He was an absolutely fantastic footballer.
Jimmy Greaves. Not just for his goal scoring feats but as my Father says about him “he’s the closest player to Messi that’s ever played the game”. And look at his goal scoring feats haha! Never talked about like George Best is despite being a better player.
A random one - Gareth McAuley. West Brom were a solid Prem team when he played for them. In his final season he got a lot of injuries, played just 12 games, and West Brom got relegated.
And I know you asked for non-City players but I have to mention Sergio Agüero. He’s massively underrated (despite the plaudits he does get). He’s scored more goals in his career than Ian Rush, Thierry Henry, Alan Shearer... of players who’ve spent most of their careers in England, only Jimmy Greaves and Dixie Dean have scored more career goals than Kun.
And look at the quality and difficulty of his goals, some of the angles he scored from, the distance he scored from, the amount of defenders he had in front of him, how many times he found that spot just inside the post where the goal keeper is never getting it, or how many times he hit the top corner...
But not just his goal scoring, his general play has always been brilliant and he adapted his game after Pep came in (some were saying he wouldn’t make it with Pep and be sold!). He’s got the best one-touch play in and around the box in our team, and he’s strong as fuck.
Even among City fans he’s underrated, he’s probably the best and most important player who’s played for us since the takeover, not many talk of him at that level though with most putting David Silva above him (there’s no way Silva is above Kun!).
