The Sunderland midfielder backs his team-mate to have a big impact.
Manager Sam Allardyce brought the Tunisian midfielder to the Stadium of Light from Bordeaux for an estimated £9 million (The Guardian) but the 25-year-old has looked the business early on his career in the North East.
By virtue of his speedy transition to English football, Cattermole is excited about seeing how good Khazri can be with a good pre-season under his belt, though it remains to be seen which division Sunderland will be in next term.
Allardyce's side sit 18th in the Premier League table, one point behind 17th-placed Newcastle United with a game in hand.
“We’ve played a lot better in games for a while now,” said Cattermole, via the The Chronicle.
“If we do stay up, then on the back of this season, I think the four lads the gaffer has brought in have been great.
“Maybe not so much Dame (N’Doye) because he hasn’t had the time, but with Wahbi (Khazri), I believe if he gets a good pre-season, he could be a real asset for the club. He could be great.”
Sunderland host Chelsea and Everton over the next six days, before visiting Watford on the final day of the Premier League season.
