Arsenal are definitely out of it, but Chelsea are still right in the running.
Chelsea vs Man Utd, that'll be a huge game. If Utd win against Blackburn and Chelsea, they'll be crowned champions at Stamford Bridge - Chelsea won't want that!
If Chelsea beat Wigan tonight, and Man Utd next week, they'll be joint top.... still all to play for, but you've got to favour Utd cause of their form.
