Reggie_Perrin On the one hand they have a player who will undoubtably have an impact, but on the other hand they will have a player on 15 million a year - and I don't see Man City picking up that entire tab. Yes he's good but what else could you do with £300K a week?
I think Everton will have the same issue that Villa had when he was there. Their tactics will increasingly revolve around him as an individual and while his "skill" will paper over some tactical cracks and help them grind out some results it will be to the detriment of the team overall.
I cite Villa as the example. Their methodology became "pass the ball the Grealish and let him win a free kick". Getting rid of him turned out to be the best thing they could have done.
