Former Tottenham star Robbie Keane "would put you straight out" which Edgar Davids found to his cost back in the day.
The pair were involved in an altercation when they played together in north London as the Irishman looked to stamp his authority.
Details of the clash have remained under wraps for years but Jamie O'Hara has finally dished the dirt.
Davids had just signed from Inter Milan in 2005 following a stellar career with the likes of Juventus and Barcelona but Keane, who was Tottenham's leading light at the time, was keen to take him down a peg or two.
The Irishman was taking boxing lessons and they came in handy once he and the Dutchman squared up.
He told TalkSport: “I tell you who had a bit about him – Robbie Keane,” said O’Hara. “I remember a story with him and Edgar Davids.
“We were at training and Davids came in from Inter Milan and he thought he was the bee’s knees. He thought he was the guy and the main man and everything, but everyone realised Robbie Keane was the main guy at Tottenham at that time.
“I remember him giving it to Keano in training and they were having a barney, and I think he tried to step to Robbie Keane and say something – and Keano just sparked him, bosh!
“He just went, bang – one punch. Gone.
“Then Davids has just picked himself up and walked off – and that was it.
“He came in the next day like, ‘morning, Robbie…’
“Everyone knew – you don’t mess with Keano. He had that thing about him that if he switched he would put you straight out.”
