DP, I don't think Nasri (and Clichy, for that matter)'s leaving because of a lack of ambition from Wenger/the board. For me this comes down to money. If he didn't believe we're going in the right direction as a club, he wouldn't have been in continual negotiation over a new contract. I'm willing to bet that city are going to give him an enormous salary next season, provided he goes there.
