Lamine Kone has told Sky Sports News HQ he has asked to leave Sunderland.

The Ivory Coast international was this week the subject of an £18m bid from Everton, according to Sky sources.

"After a week in which there has been a vast amount of speculation with regard to my future at Sunderland Football Club, I think that it is only fair to the fans of the club to clarify the situation," Kone told Sky Sports News HQ

"At the end of last season I was told by the club that I would be offered a new contract.

"Following numerous phone conversation and face-to-face meetings, the latest of which took place today with David Moyes and Martin Bain, no contract has been forthcoming.

"It is therefore with much regret that I can only assume that I do not figure in David Moyes' future plans.

"With that being the case it is with much sadness that I have asked the manager and the chief executive to be allowed to leave Sunderland Football Club.

"However, until that time I give my word that I will give my utmost in training and on the field."
