Yeah that was a bit of non-sense really but probably added as an attention grabber.
It comes down to his legacy and what he wants. To me there is an element of things being tainted at a club like City. He may not feel that though. Even we have more living history than City and that's the sort of thing I can't reconcile. I can't understand wanting to go there. Winning a bunch of trophies on a pile-on team isnt impressive.
Arsenal, United and Liverpool have some credentials. Ourselves, Spurs and Everton also have credentials but Chelsea and City are tainted.
I am happy for teams to go off into a super league and take Jack with them if he really wants. Since money has come into the game leagues risk becoming a glorified Scottish League with two boring ass teams that dominate. City and Chelsea run the risk of doing that too.
The actions of a few clubs have taken the heart out of the game where a pure player like Grealish could become just another player.
