In details published by the Sunderland Chronicle, Keane details the events that took place during Reading's 2-1 over the Black Cats back in late 2007.
You may remember Stephen Hunt popping up with a couple of goals to seal a vital win for the Royals against Keane's Sunderland who were also struggling at the time.
However it wasn't just Hunt's late winner which got under the skin of the former Manchester United midfielder but the apparent actions of then Reading Assistant Manager Kevin Dillon, as Keane describes.
"It was the first half, a tight game. Maybe the pressure was building on me - I don't know. Steve Coppell was managing Reading, and he had a couple of lads working with him, Wally Downes and Kevin Dillon. I looked across at their dugout, and Kevin Dillon was looking back across, calling me a w*****r.
"I go ‘What - me?'
"He goes, ‘Yeah, yeah. You're always on at the f*****g referee.
"I said nothing back. I never got involved with opposition managers or staff - never."
But it was only after Hunt's controversial second goal that Keane truly lost his cool....
"The players were getting themselves organised, and I was waiting for my staff to go in for a drink with Steve Coppell and the Reading lads. I didn't want to but I kept thinking ‘We're Sunderland - we'll do things properly.'
"The staff were taking ages, so I said ‘I'll go on lads. Follow me in.'
"I walked into Steve's office. Wally Downes was there and their director of football, Nick Hammond. Kevin Dillon was sitting down.
"I go ‘Well done lads, well done.'"
"As I was talking to Wally, Kevin Dillon stood up and goes, ‘Don't you come in here and -'
"I grabbed him, got his head on the table, pulled his tie up.
"‘I'm f*****g warning you -'
"Nick Hammond grabbed me. ‘What are you doing?!'
"‘You f******g -'
"‘Get out of our office!'
"I went ‘F*** yis anyway.'
"Dillon said, ‘What are you having a go at me for? I'm a Sunderland man'. I went ‘F*** you and I walked out."
There have long been rumours of this bust up floating around, with some suggesting they centred over the sale of Reading full-back Greg Halford to Sunderland who had hardly played well but there's no mention of that here.
For more on that day you can read further quotes in the Sunderland Chronicle, or just go out and buy the book which has already created plenty of debate.
