This has led Roy Keane to lambast some of the club's stars, their defenders, in particular.Speaking to Sky Sports ahead of Manchester United's 3-0 win against Tottenham yesterday, Keane said:"Ole Gunnar Solskjaer is really worried about the chances they're giving up. They need to show some character. Maguire and Shaw last week, they were an absolute disgrace to the club.

The Englishman has not been in the best of form this campaign. Keane launched a seething attack on the defender, claiming that the Manchester United captain lacked professionalism. He said:"I heard Maguire talking during the week, there's no emotion behind it. Shaw's fallen back into his old habits from a few years ago. Maguire needs to sort his game out. It's nothing to do with fitness, it's just a lack of professionalism. There are clearly talented players at the top of the pitch. Midfield and defensively you do worry. I heard Maguire talking during the week, he was like a robot. He was like, ‘Err, uh, err, apologies to the fans.’ No emotion behind it!"Maguire started in defense for Manchester United in the 3-0 victory against Tottenham. Despite a much-improved performance from the whole team, the defense did not have too much to worry about on the night, as Tottenham failed to register a single shot on target during the game.Harry Maguire@HarryMaguire93Huge reaction.
