England international Cole moved to Chelsea in a deal which pocketed Arsenal five million pounds ($9.35 million) and gave the club the services of Gallas.

Asked on Friday if Gallas was one of the best defenders in the world, Wenger said: "I think he is. He lets his performances talk for him and he's a winner."

He added: "He has integrated very well and he gives us that little bit extra.

"I feel we are strong but have a lack of experience. But with Gallas you feel that extra bit of experience is there."

Wenger was quick to play down talk of his 10th-year anniversary at Arsenal although he did say he has no desire to match Manchester United's Alex Ferguson and serve for 20 years.

Wenger said: "You must act every day like you will have your whole life there but you must accept it can end tomorrow."
