Sunderland have confirmed that midfielder Alfred N'Diaye has joined Turkish outfit Eskisehirspor on a season-long loan deal.
The 23-year-old, who arrived at the Stadium of Light in a £3.8m move in January, made 15 starts for the Black Cats last season.
However, he found himself out of manager Paolo Di Canio's plans for the new campaign.
N'Diaye has three years remaining on his current contract at Sunderland.
