The best option for him is to leave. I'd have loved to see him play for Juventus... That's if they're interested but having to cut their wage bill, they might not look his way.
Monaco looks more likely and having a good relationship with Thierry Henry from Arsenal and Barcelona might be a plus too.
It is unfortunate that Cesc isn't getting enough time, maybe it is time for him to really move from London.
Chelsea for me was never his kind of team.. Yeah... High time he left.
