I actually agree with Keane. There were a few occasions he was strolling about with others around him pressing or slowly jogged back as Sheffield United attacked.
I'll give him the benefit of the doubt as it was the first game back after a long time, but I don't think what has been said is particularly harsh.
I know the 'wry smile' is a bit of a football cliche and people do react in that way to a mistake. That said, I've felt my blood boiling a few times seeing Mings piss about with the ball for no reason, ending in him almost giving a goal away and seeming to find it very funny. Don't think it would bother me if it didn't happen every game.
