Manchester United legend Rio Ferdinand has revealed the moment hot-headed Roy Keane lamped team-mate Chris Eagles in training.
Eagles, 35, joined the Red Devils academy in 2000 before being promoted to the first team three years later.
The winger managed 17 appearances in five years for the club and had four loan stints before joining Burnley permanently in 2008.
Speaking on the VIBE with FIVE podcast, the ex-defender said: “I remember when Roy Keane punched up Chris Eagles one time.
“He (Eagles) was only [a] young kid, (taking) liberties. It was good for him Eagles.
“Roy must have been coming back from an injury, or he didn’t play, and he was playing with the reserves and the youngsters that were in there like Eagles and Lee Martin were like rats, getting in close and trying to tackle.
“He went in late on Roy once or twice and Roy said to him, ‘Listen, slow down’. The ball comes in again, Eagles was trying to impress, trying to leave him mark and left a little bit on Roy again and pulled his jersey.
“Roy just turned round and went bang in the jaw. A quick short jab and I just stood there and went, ‘Roy, what’s wrong with you?’.”
