Gallas was named as Thierry Henry's successor as Arsenal captain by Wenger ahead of Gilberto Silva. Wenger has now informed former Chelsea defender Gallas that he must be an example to the rest of the Arsenal side on and off the pitch "William's now an example. Not only on the the pitch but off it. Of course, I told him about that," Wenger told the Daily Star. "The captain is like a manager. I was one as a player and knew what you can do and what you cannot. "This season he is a very positive influence and I don't believe it's a special risk. The captain's job is important but what is more important is team spirit.
