Sunderland boss David Moyes speaks after losing to Middlesbrough in the Tees-Wear derby. Sunderland manager David Moyes remains hopeful Lamine Kone will stay at the club, despite a reported £21 million bid from Everton and continued speculation regarding the defender's future. Moyes confirmed he turned the offer down due to a belief that he would not be able to sign a replacement for the 27-year-old but didn't confirm the move had been rejected outright by the Sunderland board. "Kone will stay," Moyes said.
