Arsenal boss Arsene Wenger admits they've missed Mathieu Flamini since his summer move to AC Milan.
He told arsenal.com: "I don't deny the quality of Flamini but he wanted to go. I didn't want him to go" Wenger said ahead of the victory over Manchester United on Saturday. "Today, we do it in a different way and we have to show we can be just as efficient.
"I think Denilson had an outstanding start to the season, he is going from strength to strength and Alex Song can play that role too."
