I won't quite write them off yet, but now all eyes should be fixed on Man U, because the title is theirs to lose - unless they slump to a couple losses they will shuffle limply straight into the title regardless of what Arsenal, Chelsea or Man City do.
Too much time on my hands statto arithmetic:
Extrapolate up to 25 games between the current top 3 - if Chelsea 41(23) beat Man Utd 48(22) both times, it'll equate to 48-47 with Man Utd having a game in hand. Arsenal 46(23) beat Man Utd 48(24) will result in Arsenal 49, Man Utd 48, Chelsea 47 - with Arsenal still having a game in hand to go to 52.
Man Utd's two matches against Chelsea are crucial to them winning the title so they have to either win both, or one and also the match against Arsenal. For this reason as an Arsenal supporter, I am mercenary enough to be cheering on Chelsea's resurgence at the best possible time - after Arsenal's already done playing them.
Extrapolate up to 38 games between the current top 4 - assume all other matches are wins, and Man Utd and Chelsea both beat Man City - the final table will be Arsenal 91, Man Utd 87, Chelsea 86, Man City 81. Obviously it won't be this perfect - Spurs may pip Man City to 4th spot again - and any loss or draw to a lower-table team can really throw a spanner into any of these four teams' title challenge, so every game is crucial so to speak with this season being so close. Only Arsenal can afford to lose a game from here on in and still guarantee the title with 88 points - but NOT if that loss is to Man Utd who would then leapfrog them with 90 points. That's the one match both Arsenal and Man Utd *must* both win so in my mind their clash in the third last round at Ashburton Grove will be the title decider, so it should be a real cracker (will Arsenal go to pieces under the pressure again and lose 0-3? Will it be Park who'll be motm again by playing a blinder as usual against the Gunners?).
And further down the table, Liverpool's best possible result if they win *every* game from now on is 74. A CL spot is beyond reach, so Dalglish's only realistic target is to overhaul Sunderland's 8 point lead on them, which is obtainable as they have a game in hand over the Black Cats.
