This is dribbling. Foden destoyed some of the best in the business. Pay particular attention around the 36 second mark where you will see him ride heavy tackles in quick succession, summat Grealish never does.
The thing is, and I'm not sure if this is me being naive, but one of Villa's main threats will likely be set pieces with the height Mings and Konsa bring to corners/free kicks so I wouldn't be surprised if Grealish goes down/wins free kicks for that reason.
If he joined us, where we're shit at set pieces, then I doubt he'll do the same. Unless Pep comes up with a typical Pep-esque plan where it can be used to our advantage.
Like I said, maybe naive, but I don't think Grealish winning free kicks is part of his game by default and could easily be ironed out if need be.
On a separate note, that video just reminded me: how fucking good is Phil? Christ.
