Sir Alex Ferguson has revealed he turned down the England manager's job on two separate occasions during his Manchester United reign.
The Scot states in his autobiography, which is released on Thursday, that he was asked to become England boss in succession to Glenn Hoddle and Kevin Keegan.
Ferguson rejected the offers out of hand, though, saying: "There was no way I could contemplate that. It wasn't a bed of nails I was ever tempted to lie on."
Former United captain Roy Keane comes in for criticism in the book, which follows on from his last autobiography spanning from 2000-2013.
Ferguson reveals that Keane was livid at the club over their pre-season training camp in Portugal. The Irish midfielder said the accommodation was not up to scratch.
Then Keane tore into his team-mates in an interview with the club's in-house TV station MUTV.
Ferguson says in the interview, which was pulled, Keane "slaughtered" several of the club's senior players.
Keane then suggested the squad watch the interview and a furious row ensued. Ruud van Nistelrooy, Edwin van der Sar and Carlos Queiroz all argued and Keane then accused Ferguson of bringing his own dispute with shareholder John Magnier over the Rock of Gibraltar racehorse into the club.
"It was frightening to watch. And I'm from Glasgow," Ferguson says.
"He has the most savage tongue you can imagine."
Ferguson sold Keane to Celtic. The Irishman returned to Carrington to apologise to Ferguson months later, but the two have clashed since.
David Beckham was also a big part of Ferguson's reign at Old Trafford.
Just like in his first autobiography, Ferguson talks about how disappointed he was to see Beckham regarded as a celebrity.
The Scot talks about his annoyance at the interest in Beckham's hair and not his performances on the pitch.
Ferguson also talks about the infamous moment, after an FA Cup game against Arsenal, in which he kicked a boot in the United dressing room that struck Beckham above the eye, requiring him to have stitches.
"David swore. I moved towards him, and as I approached I kicked a boot. It hit him right above the eye," Ferguson says.
Ferguson told Beckham he had let his team-mates down in the match and said that he decided to sell the former England captain shortly afterwards.
