Roy Keane's second autobiography - entitled 'The Second Half' - goes on sale to the general public later this week and, as you might expect, it contains several juicy anecdotes from the Irishman's eventful 12-year spell at Manchester United.
Various media sources and individual journalists have been discussing various parts of the book throughout Monday afternoon, with arguably the most explosive and entertaining revelation - aside from that Peter Schmeichel fight - so far relating to Keane's now infamous falling out with Red Devils icon Sir Alex Ferguson and former assistant boss Carlos Queiroz.
"He was just on my right shoulder; how I didn’t f*****’ hit him again – I was thinking, ‘The villa in Portugal, not treating me well in training – and he just used the word “loyalty” to me," Keane fumes about Queiroz - Ferguson's right-hand man at Old Trafford in two separate spells between 2002/03 and 2004/08 - according to the Daily Star.
"I said, ‘Don't you f****** talk to me about loyalty, Carlos. You left this club after 12 months a few years ago for the Real Madrid job. Don’t you dare question my loyalty."
After an attempt from Ferguson to stop the disagreement which is believed to have been sparked by Queiroz criticising Keane's controversial interview with MUTV, the latter reveals how he turned the attentions of his formidable wrath to his manager - something we imagine few Manchester United players ever had the confidence to do before or since.
"You as well gaffer. We need f****** more from you. We need a bit more, gaffer. We’re slipping behind other teams," he said.
With his relationship with Ferguson having seemingly deteriorated beyond all repair, Keane eventually left Manchester United to join Celtic in 2005.
His stint in Glasgow was to last for just a matter of months, however, with a long-term hip injury forcing him to reluctantly announce his retirement from the game.
The rift between two of English football's most iconic names has not healed over the years, with Keane - in his role as a typically no-nonsense television pundit - accusing Ferguson of not knowing the meaning of the world loyalty following the Scot's decision to release a new book of his own last year in which he did not hold back on several of his former players.
Having moved on from television duties, Keane now serves as assistant manager to both Republic of Ireland boss Martin O'Neill and Aston Villa's Paul Lambert.
