Sunderland have announced the signing of Tunisian midfielder Wahbi Khazri from Bordeaux on a four-and-a-half year deal rumoured to be worth £8.5m.
The 24-year-old, who will wear the No.22 shirt, is the Black Cats' fifth new arrival of the month, joining Jan Kirchhoff, Dame N'Doye, Steve Harper and Lamine Kone at the Stadium of Light as they fight for Premier League survival.
"Wahbi is a quick, dynamic attacking player," Sunderland manager Sam Allardyce told the club's official website. "He has many attributes, not least his delivery from wide areas and set pieces and of course his ability to score goals.
"His versatility will certainly complement our existing forward options and I am delighted to welcome him to the club."
Allardyce's charges currently sit 19th in the Premier League table, four points from safety with 15 games remaining.
