I think Bayern are the most likely. They could use him, since Robben & Ribbery are getting old. Wenger will want to sell outside the PL as well.
PSG I don't think so, it's obviously not all about the money with him and PSG & French league aren't that attractive for a competitive guy like him.
Chelsea would probably be his favoured destination. Gets to stay in London, competes for everything, and gets the wages he wants. But Wenger will do his utmost to prevent selling to another English team.
City might try but he was already benched by Guardiola at Barca was he not?
Outside chance for the likes of us, Juve, Real, or staying at Arsenal. I think Ozil will stay.
