Former Manchester United boss Sir Alex Ferguson has refused to hold back in his new autobiography.

The 71-year-old legendary manager has had his say on a number of issues surrounding his 26-year reign at Old Trafford.

Ferguson was particularly critical of his former captain Roy Keane.

Keane played a vital part in Manchester United's success during his 12-year spell at the club before leaving acrimoniously after he blasted the likes of Darren Fletcher, Alan Smith and Edwin van der Sar on MUTV for their performance against Middlesbrough in November 2005.

Keane moved to Celtic fairly after the affair and Ferguson has not seen eye to eye with the Irishman ever since.

Ferguson was right to allow Keane to move on, as the midfielder was not the same player as he once was.

Keane was one of the best box-to-box midfielders in his day but he was coming to the end of his career when Manchester United decided to move him on.

Ferguson says in his book that Keane started to think he 'was the United manager' which the Scotsman has every right to be displeased with.

However Ferguson was wrong to lambast one of the most influential players of his era at the club.

Keane hit back last night by questioning Ferguson's loyalty by saying: "In my opinion he doesn’t know the meaning of the word."

The Red Devils former captain is right in questioning Ferguson's motives as his behaviour is extremely hypocritical.

Keane led Ferguson's side to seven Premier League titles, four FA Cups and a Champions League - the least he deserves is a bit of respect from Ferguson, even if they are no longer on speaking terms.
