Arsenal have already sold Robin van Persie and Alex Song this season, and Wenger is not keen on keeping anyone who "doesn't want" to stay.
According to reports, the 23-year-old international could be sold for a fee of over £12 million pounds and Manchester City seems to be keen on taking him. Jack Rodwell has been City's only new signing this season and coach Roberto Mancini is on the lookout for a winger to fill in the space left open by Adam Johnson.
Liverpool may also show some interest in the deal.
Walcott joined Arsenal in 2006 from Southampton and has appeared in 220 matches for them.
Who wants Walcott?
