I don't know what all the fuss was about with his book, he is entitled to his opinion on his own career.
All the former United players he was critical of reacted as expected, Roy Keane had a bit of a rant, Beckham and the others weren't bothered because the incidents that were brought up were hardly new revelations and they had made their peace with Fergie a long time ago.
The only people that had any major issue with the book were ABU's who used it as the latest in a long line of excuses to attack Fergie and by extension United.
It shows just how thick these people are that they actually thought that Fergie would give the likes of Liverpool or Man City an easy ride, he was never known for his diplomacy so a book was never going to be any different.
Obviously he dropped a few juicy comments in on purpose but he's hardly the first celebrity to do that....controversy creates cash.
