The Daily Mail says despite interest from clubs in France, Wenger will let Gallas leave in January only if he can secure a replacement and trust the defender not to stir up more trouble.
"William is a player I rate and a man I rate as well," said Wenger yesterday. "I have a big respect for him. He was working as a captain under big pressure from the press and, at some stage, you do not want this high pressure to affect him or the team.
"He is a player who is committed to the club. He took to heart all the problems of the team. This can be a new start for him and he can be stronger as a player. We have to close this subject now."
