#10. Wahbi Khazri – Watford – £9 Million
Sunderland signed the attacking midfielder from Bordeaux for £9 million. The Tunisian international has impressed in his two seasons for the French club, scoring 13 goals in 40 games from midfield. He stands at six feet tall, and Khazri is known for his excellent free kick ability. Sunderland’s side is crying out for another player in the midfield alongside Yann M’Vila – who has been excellent at times this season. Khazri made his debut as a second half substitute in the loss against Manchester City, but Sunderland fans are yet to see the best of the Tunisian attacking midfielder.
