No stranger to controversy himself as a player, Sunderland boss Roy Keane believes Arsenal captain William Gallas has a right to criticise his team-mates. "I used to quite a bit," Keane told Sky Sports News when asked if Gallas was wrong to criticise.

"But there are ways of doing it. You just hope you have a strong dressing room.

"Obviously I'm not going to comment on what the captain of Arsenal has allegedly said.

"But you hope you have a few captains in your dressing room to take care of things.

"I was lucky in my playing days that we had some strong characters and we used to deal with what ever was going on in the dressing room.

"If I was missing something, which I very rarely did, then there was another couple of players to spot things.

"A good dressing room and a good captain can make the manager's job easier.

"Everyone has the right to say what they feel every now and again and if it upsets people, so what? People are too easily upset these days."
