Wanting out is one thing, but he shows a serious lack of class when he talks up the possibility of joining Man Utd. That shouldn't even be a consideration.

Wenger is a weak manager and this is why he has to go. All the bollocks about keeping the team together and unity will never work under him because he can't even keep his players happy. This grand plan of his is flawed anyway because there is no guarantee that you'll team will start winning trophies because they've played together for years. Familiarity breeds contempt. Keep such a flawed system in place and we'll keep seeing this every few seasons. Players will grow tired of each other and the mistakes, then they'll grow tired of the manager for not addressing it.
