To say he's been an "average signing" is very unfair.
He's a different player to the Grealish that was at Aston Villa, At Villa Dean Smith gave him a free role basically allowed him to play anywhere. It's different for him under Pep were he's told to stay high and wide and hold his position.
I think he's been superb for us, He's doing what's asked of him under Pep, He was sensational in the treble winning season, Unfortunately he picked up injuries last season but the games he did play he was really good.
The media in particular are judging him on his goals and assists which is pretty silly especially with the job he's been asked to do in our team, He's brilliant at what he's does and that's making the pitch as big as possible, Attracting players to the ball, Making space for his team mates, Keeping possession and winning fouls.
Anyway everybody has there own opinion on Grealish, Me personally I'm a big fan of his game.
