Arsenal boss Arsene Wenger is delighted with his deadline day capture of former Chelsea midfielder Lassana Diarra.

"I was very pleased to get him," he said. "I like him as a player he is very good defensively with a good fighting spirit. He is young as well so we can create a unit of very strong players in the same position. He is versatile. He can play right back or left back as well as centre midfield. But I think basically he will be in central midfield."
