I think Grealish takes too many unnecessary touches (on the ball).
That's the difference between him and players such as Neymar, Messi and Silva before him.
I mean I do agree -
But again I don't think that these unnecessary touches effect him if he played for United compared to how it does at City.
For City, the whole opposition usually are just sitting deep on a different level and the passes that break open the opposition need to be passed in to the right team mate at the right time.
Its not like at United where its Bruno Fernandes creating the chances and the tempo of the whole team and players like Rashford, Martial, Sancho can focus on taking on their player by making runs at them or runs behind the defenders - the whole man City team is able to do it from De bryune, Gabriel Jesus to Rodri to Zinchenko.
I just don't see Grealish being good there, his game is showered, unable to do his best things whilst it's the same for City- the game is slowed down from Grealish in their teams compared to Sterling and Mahrez or Sane etc.
