Arsène Wenger says loan signing Kim Kallstrom could have "a major impact" on the final weeks of Arsenal's season.

The Sweden international joined the Gunners in January but arrived with a back injury and has yet to make an appearance.

Kallstrom could make his debut in Sunday's north London derby at Tottenham and Wenger believes the 31-year-old has a significant role to play.

His motivation and attitude has been spot-on

“I think he can play an important part in the end of our season," said Wenger. "We are all absolutely delighted to have him with us because on a daily basis he is a joy to watch.

“He is a fantastic guy. His motivation and attitude has been spot-on. His readiness to put the effort in has been spot-on.

"As I explained we did not pay [while he was injured], we found a good agreement with Spartak Moscow and it was at the end of the day so it was a case of signing him or nobody.

“Now that Jack, Aaron and Mesut are out we are happy to have him. He could end up having a major impact on our season.”
