Joey Barton has lifted the lid on the row which led to his Newcastle United exit in his new book.
Barton was given a free transfer by the club in the summer of 2011.
In his book "No Nonsense", Barton said: “When Fabricio Coloccini, who spoke little English, was named as Newcastle’s new captain I knew my days were numbered, and that the club was changing around me.
“I was officially recognised as vice-captain, but when Coloccini missed a pre-season friendly against Leeds United at the end of July 2011, I was overlooked again.
“That was a deliberately provocative act, since it belittled me in the eyes of my team-mates. I went mad, told (Alan) Pardew to **** off, and refused to shake his hand before the game.
“He took offence, and everyone else took to the trenches.
“I was ordered to train alone, and made available on a free transfer.”
Barton, suspended from Rangers following a verbal exchange in the wake of the club's 5-1 defeat to Celtic, took to Twitter after being transfer-listed by the club.
He tweeted at the time: “Somewhere in those high echelons of NUFC, they have decided, I am persona non grata. I am on a free but the honour of wearing those black and white stripes, surpasses that.
“One day the board might realise, what the shirt signifies. HONOUR and PRIDE. Thanks for your continued support.”
In his book, the 34-year-old said: "I wasn’t going to bow and scrape to the likes of (Derek) Llambias and (Mike) Ashley.
“I was at war with them, and had the means to answer back on my own terms.
"Newcastle United sent me a legal letter, warning that I would be in breach of contract if I used my Twitter account to comment on club affairs, but it was too late, the genie was already out of the bottle.”
