Not necessarily, I'm just saying if the style's don't match, who's to blame? And I'm not really defending Barkley, who I agree has looked selfish.
What I am saying is that it is the manager's job to get these guys playing to the best of their abilities. If management thinks that the manager isn't getting the best out of the players, I would say the manger needs to go, not the players.
There's a long way to go in this season, and although I'm pessimistic, it would be stupid to sell Barkley or sack Martinez at this point. Rash, emotional decisions are not smart business.
