Alex Ferguson's new autobiography has certainly made a huge impact since it was launched yesterday.
The biggest issues have revolved around his fall-outs with some of his former players.
But it is his former captain at Manchester United, Roy Keane, who receives the most criticism between the covers of the book.
Former Ireland player and manager John Giles was on The Pat Kenny Show this morning to give his take on the revelations in the new book.
Giles is critical of Ferguson's decision to release a book, particularly at this delicate time for his former club under successor David Moyes.
"I don't see why he should do a book on it now and rake up some of the controversial incidents that happened in his career, particularly at a very sensitive time for the club. I don't think there is any excuse for Alex Ferguson to bring out a book at this particular stage. The best thing he could have done was to disappear for at least a year," said Giles.
The former Leeds legend does not think Ferguson's actions are in the best interests of the club. That flies in the face of his past decisions regarding David Beckham and Keane, which he believes were in United's interest.

"Roy Keane was a great player for Manchester United and a great player for Ireland. My take on it is when Keane was at his best, Alex Ferguson gave him a lot of rope. And when Keane criticized his team-mates [in a 2005 interview on MUTV], it wasn't right. He was coming towards the end of his career and not playing well. That's when Ferguson took action," said Giles.
"I think Keane was a bit naive because that's what happens in football. You're only as good as your last game. The manager cannot afford to be sentimental. But it could have been handled a lot better. However, Ferguson's obligation was to the club and if he felt Roy Keane wasn't doing it like before, then he had to let him go."
As for David Beckham, Giles believes there is a simple explanation for the falling out:
"In Beckham's case, Ferguson would feel he was losing control of him and I think that would be the case as well. Before he let Beckham go, Beckham was down in London where [Victoria] was working. And I know there was one time where he didn't turn up for training because he was looking after the kids when she was out doing something else. All managers worth their salt would not put up with that."
He also added that Beckham's "celebrity was mistaken for ability", even though he rates the former England captain.
