Roy Keane's latest bust-up

Roy Keane seems to display some of the classic traits of a bully - he can hand it out but he can't take it.
Some media reports of the post-MUTV session with the manager & players say that, when reprimanded in front of the players by Alec Ferguson, Keane threw the "Rock of Gibraltar" affair back in his face.
If true, this clearly had nothing to do with the situation but was the petty, spiteful response to criticism that you might expect from a spoilt child.
It's sad that a footballer of his undisputed class has such an immature personality. It's hard to imagine him succeeding in team management where player motivation would be a key requirement.
Instead of fond memories of his exploits for Manchester United and Ireland, he'll probably be remembered for the sour taste of his departures from both camps.
