New Arsenal captain Cesc Fabregas is confident William Gallas can handle a return to Chelsea on Sunday.
"William showed that he is a great professional, he played fantastic for me," said Fabregas after victory over Dynamo Kiev on Tuesday. "He has been superb for us. I have learned a lot from him and I know if I need to I can always go to him.
"Whatever happened with William is in the past and we are looking forward. We started by winning and playing well so that's the most important thing."
