Sunderland defender Lamine Kone has revealed that he has asked to leave the club this summer.

The Ivory Coast international only moved to the Stadium of Light from French club Lorient in January and proved to be a hit on Wearside, scoring two goals in 15 Premier League appearances, as he helped the club secure survival in the top flight last season.

The 27-year-old, who has been heavily linked with a move to Everton during the transfer window, has now revealed that he intends to end his stay with the Black Cats, as the club have failed to follow through on their promise of offering him a new deal.

Kone told Sky Sports: “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.”

The news will come as a major blow to Sunderland, who kick-off the new Premier League season with a trip to the Etihad Stadium to take on Manchester City on Saturday, but Kone insists he will continue to give his all for the club despite his desire to leave.

He added: “However, until that time I give my word that I will give my utmost in training and on the field.”

Sunderland are available at 12.00 to begin the new campaign with a victory while the Citizens are on offer at 1.25 and the draw is priced at 6.00.
