Sunderland AFC have completed the signing of midfielder Alfred N'Diaye from Turkish club Bursaspor for an undisclosed fee.

The 22-year old Frenchman arrives on Wearside after putting pen to paper on a three and a half year deal at the Stadium of Light.

N'Diaye, a France Under 21 international, began his career at French Ligue One side Nancy before moving to Turkey in 2011.

Sunderland AFC manager Martin O'Neill said: "Alfred is a strong, powerful young player and as such can offer us more strength in depth.

"He will give us options and I'm delighted that we have been able to bring him to the club."

N'Diaye will wear the number four shirt for Sunderland.
