Roy Keane has claimed that the Manchester United dressing room was "weak" under the management of David Moyes.
Moyes was sacked after just 10 months in charge of the Red Devils and Keane believes that the main reason was due to the poor performances and attitudes of his players.
"I look at the current players, and they should have been doing a lot better," he wrote in his new autobiography.
"It might be argued that it was up to the manager to motivate them. But not liking a manager, for whatever reason, can never be an excuse for not going out and doing your best.
"Looking at what happened to David Moyes, I have to conclude that he can't have had a strong dressing-room: he had a weak dressing room."
Keane is currently the assistant manager of the Republic of Ireland and Aston Villa.
