The Tunisian has shown himself to have a fierce cross.
So far the new arrivals have looked like good additions, especially Tunisian international Wahbi Khazri. The 25-year-old joined from Bordeaux last month and has looked a real talent in his early outings for The Black Cats.
One aspect of his game that has certainly drawn the eye is his crossing ability. He can whip in a mean delivery and it is an aspect of his game former Sunderland striker Niall Quinn would have relished.
Speaking to Sun FM this week the former Sunderland player and chairman has commented on the player - comparing him to former team-mate Michael 'Micky' Gray:
"Teams are starting to cross the ball again. The game is evolving.
"It is really refreshing to see and Khazri can do that. What happens is the players start to read it then. If it is coming more often, then you know what's happening.
"It gives you an advantage. Half a yard as an attacking player and you can find a bit of space knowing that the ball's coming in.
"Micky could do that. Micky probably laid on the most famous goal I scored in a Sunderland shirt anyway. I scored a header against Newcastle and Micky ran the length of the field and whipped one in for me. So I have every reason to be grateful for Micky Gray.
"I just hope that the likes of Jermain Defoe and others feel the same way with Khazri come the end of the season."
Gray was with Sunderland for 12 years as a professional and in that time earned a reputation for his wand of a left-foot. It even helped him win three England caps in 1999.
Khazri's delivery is certainly on par with the former Black Cats hero and if he continues to deliver with such mean accuracy, Sunderland should be benefiting with plenty of goals.
