Winks and Mount play in a midfield 2 for England, with Grealish as the LW. In Aston Villa, Grealish also plays as a LW, although he can also play as an AM, like Bruno. So if Grealish comes here, his competition will be Rashford or Bruno. Maybe even Greenwood, if he can play on the right.
It will not be Pogba, who is playing as a CM in a midfield 2 for us. To replace Pogba, we need a player who can play in a midfield 2, like how Mason Mount was playing for England yesterday. Not Grealish, who is at his best closest to goal. Playing Grealish in a midfield 2 with Fred/McT will be a disaster, because Grealish is just as weak defensively as Pogba is, and because Fred/McT have shown they are not good enough to be playing as the sole anchor in midfield for us.
I hope we sell Pogba, get a proper CM in, and also get Grealish, so that we have some creativity from the wider areas. This would be a great and very well balanced team :
---------Philips--Fred
Mason--Bruno--Grealish
-------------Martial
Imo Grealish is a very good player, but not as good as Bruno. He is better than Rashford though.
