Roy Keane is being investigated by the FA following the admission in his autobiography that he deliberately tried to exact revenge on Manchester City’s Alf-Inge Haaland.

The Manchester United skipper could be charged with bringing the game into disrepute following his confession that he intended to harm Haaland.

FA spokesman Adrian Bevington confirmed that an invetsigation into Keane’s remarks would be forthcoming.

‘We have looked at the comments by Roy Keane and given them some consideration, but our view is that, at the moment, it is part of a serialisation and we would like to see the full context before making a decision.

‘However, we certainly would not expect any one player to set out to physically hurt an opponent.’

Keane stated in his book: ‘I still hadn’t forgotten him (Haaland). Now it was Man City at home, his new club fighting relegation.

‘I waited until five minutes from the end. I f****** hit him hard. I think the ball was there.

“Take that you c*** – and don’t ever stand over me again sneering about faking injuries – and tell your pal Wetherall (David) there’s some for him as well!”

‘I didn’t even wait for the ref to show the red card.’

Haaland, who has barely played since the tackle, has been reported to be contemplating taking legal action against Keane.

The Keane incident was seen as retribution foran incident three years earlier when a clash with Haaland saw Keane mmiss the best part of a year through injury.
