Premier League outfit Sunderland have completed the signing of French youngster Alfred N'Diaye.
The 22-year-old has arrived on Wearside for an undisclosed fee from Turkish side Bursaspor.
"Alfred is a strong, powerful young player and as such can offer us more strength in depth," manager Martin O'Neill told the club's official website.
"He will give us options and I'm delighted that we have been able to bring him to the club."
N'Diaye has signed a deal at the Stadium of Light until the summer of 2016.
