The midfielder rubbished suggestions of a fall-out despite the fact he has joined Eskisehirspor on loan, having only arrived from Bursaspor in a £3.8 million deal in January
The midfielder joined the club during the winter transfer window for £3.8 million from Bursaspor but lost his place in the team following the appointment of Paolo Di Canio in March.
The 23-year-old completed a move to Eskisehirspor on a season-long loan last month but says it has nothing to do with a bust-up with the Black Cats manager.

"We talked about my expectations because I need playing time. I'm at an age where I need to play, so it was agreed to my loan and I chose Turkey.
"After the half-season I spent at Sunderland, starting on the bench was not what I wanted.
"I am only 23, but you must play every week to progress. I could have stayed at Sunderland, but I preferred the loan."
The move sees N'Diaye reunited with his former coach at Bursaspor, Ertugrul Saglam, who is now in charge at Eskisehirspor.
He added: "I had several offers, but it is this one in Turkey that gave me the most motivation.
"I know the coach, I spoke with him and he is counting on me for the upcoming season. This offer guaranteed me the most playing time."
