Manchester United manager Alex Ferguson has told his former club captain Roy Keane he will need to become more “tolerant” if he is to succeed as a manager.
Keane is preparing for his first game in charge of Sunderland this weekend, and Ferguson believes the demanding Irishman has to curb his temper and accept the limitations of others.
Ferguson told the Daily Mirror: “I wished him well and told him he will have to learn to tolerate things in football that he just doesn’t agree with.
“The most important thing he has to do is find a way of enjoying the job.
“Some players think they know what it’s like to be a manager but they don’t know, they can’t do. You’ve got to be prepared to learn and you’ve got to find a way to enjoy it.”
Keane walked out of the Republic of Ireland’s pre-World Cup training camp in Saipan four years ago, while he also often hit out at his United team-mates when he felt they were not trying hard enough on the pitch.
