After Sunderland's 1-1 draw at Wigan, Roy Keane was asked about his recent spat with FIFA vice-president Jack Warner over the club versus country row involving Dwight Yorke and Trinidad and Tobago.

The Black Cats manager said: "To be honest I've had enough of it. I've said my piece and we have to move on. If he wants to continue writing letters then good luck to him."

But reminded that Warner is seen as a potential key figure in terms of England garnering support for their projected 2018 World Cup bid, Keane added mischievously: "I hope I've jeopardised it."
