In a bombshell revelation, Wayne Rooney has shared new information on one particularly heated bust-up between Roy Keane and Sir Alex Ferguson at Manchester United.
The former Ireland midfielder left the Red Devils in 2005 following a reported fallout with his ex-boss, with both men having since spoken about what happened in their respective autobiographies.

According to The Sun, the disagreement stemmed from the then-captain giving his opinion about certain teammates following a 4-1 defeat to Middlesbrough on United's official television channel.
Keane is said to have criticised a number of first-team players, including Rio Ferdinand, Alan Smith, John O'Shea, Darren Fletcher and Kieran Richardson, during the interview that never got aired.
Ferguson was not happy with the Irishman's comments and called for a team meeting, where the whole squad got to watch the clip.
Rooney has now shed new light on what happened behind closed doors at that meeting, claiming that the manager had to be restrained from getting his hands on Keane.
"When Roy Keane left the club, it's well-known there was a meeting… I can't tell you the details of what happened in the meeting," the Derby County boss said on BBC Sounds' Tony Bellew is Angry podcast when asked about the angriest he had seen a manager in his playing career.
"Roy Keane has had a go at some of the players on the club's TV channel and Fergie wasn't happy and called a meeting.
"So Roy Keane said 'Let's all watch it together', so we've all gone into Alex Ferguson’s office, the coaches, players and Sir Alex Ferguson.
"I'm only 18 or 19 at the time and Roy has asked if anyone has a problem, and everyone said 'No'. To be fair, it wasn't that bad.
"I think it was probably a hangover from something that had gone on between Roy and the manager in the past.
"Anyway, it had gotten into an argument between Roy and the manager, and a few different things got said.
"I see Alex Ferguson jump over his desk, and I was thinking, 'Wow, this is crazy!'
"He jumped over the desk and was getting held back.
"It got calmed down but the next day Roy Keane has come into training and then about 30 minutes later we seen him driving off.
"That's the last we saw of him."
