Chelsea are only three points ahead of Liverpool in third and City three ahead of them in second. City can go top with a win and they along with even the smallest outside chance at the title all but disappear for Liverpool. Or Chelsea can go six points up with a win and put the top three all but mathematically out of the question for Liverpool. A draw doesn't look much better, putting the sides four and seven up respectively, but the more optimistic sorts might see it as the best of all possibles.
Choose your side, then. Or maybe just hope Mourinho remembers his Big Sam's 19th Century Funhouse outburst just last week and actually sets up to play decent football rather than being the hypocrite who regularly put ten behind the ball with Madrid, Inter, and in his last spell at Chelsea. Personally I'm hoping City hang five on him tonight.
