The fact that you are a much better team without him in it speaks volumes.
It is clear to anyone that isn't a city fan that grealish doesn't fit the system played at city. Especially in his position.
To play at City you have to a super intelligent quick thinking like foden or silva. Grealish just isn't that type of player he is a dribbler who likes to hog the ball. He isnt a one two touch player.
Last season I thought Rodri would never make it at City. How wrong I was.
I also thought Cancelo wasn't as good as Danilo. How wrong I was.
It can take a player a year to understand Pep's way. Don't write him off yet.
