Those odds match up to the teams in my head, I'd put Chelsea favourite if Costa was on his way out like has been suggested this season, otherwise United , after that PSG definitely because Lukaku has had his head turned one way or another maybe with Money, which rules Arsenal out.
I think it boils down to his like/dislike of chelsea or Mourinho because if Costa goes those two will be pushing most for him unless PSG come in with a ridiculous bid, that wouldn't normally stop United but after Pogba I can't see them being bitten twice, not two yrs on the bounce anyhow.
