Not going to judge Villa till I see them vs some of the sides mid table and below. Their defence looked quite solid until the final 10 mins of the game and while i've doubts over their strike force, they have a ton of interesting creative midfielders who could shoulder the goal scoring burden.
As for the Grealish stat, I think Bale had a similar statistic at Spurs a few years ago, just before he went on the run that saw him establish himself as one of the nest players in the world. Grealish will be a prem player.
