That's the beauty of a forum, different takes.
I said John Stones was world class and still our best defender 18 months ago and people laughed me off the board.
I also said Cancelo is a shite defender yet there will be many people who still overlook the obvious.
100% with you on both opinions there and something I've said myself.
As per what you said about there being a good player in there, somewhere. I, also, agree with that assessment.
Grealish is of the same type of 'flash' as a player, but in there is a, actually, really good player wanting to come out.
So, with that said, I'm not sure if there's enough room in the squad for two 'flashy' players that doesn't change the culture at the club, but I can see this being coached out of those players (I find Cancelo's in-game 'flash' annoying when he does it on the pitch at the most dumb times).
But, I want caveat what I've said about both Grealish and [possibly] Pogba being in the squad. Just recently I've seen in the Birmingham Mail online that City may be seeing the buying of Grealish as a 'mistake' and look to offload him.
I think that's just salty by the outlet but I, also, can't see both at the club, in my opinion, unless we're getting rid of midfielders in Zinny, Gundo and Bernie.
