Yep. He's clearly said he wants to leave, but respects Wenger decision.
He has no choice but to respect the decision because he is under contract. The dilemma for Wenger and Arsenal is do they now retain him and hope he doesn't go through the motions then lose him for nothing, or do they take the money now? It is a tough call as unless you unearth an unknown gem where do you get the quality of Sanchez at short notice for 50-60 million?
