Liverpool and Man City are in the driver's seat, but Arsenal's form has picked up a bit of late and Mourinho/Man Utd have a habit of getting the cards to fall their way at just the right moment.
All four teams have lost silly matches recently; Liverpool faced Southampton four times this season and failed to score in any of those matches. It gives me flashbacks to 2008-2009 when Liverpool's two limp 0-0 draws with Pulis' Stoke blew up their title chances. In both cases they were winnable games. This despite doing the double over Ferg's Man Utd.
While I accept that Manchester United are difficult to beat (so, very well done Arsenal last week-end), they don't win many matches either, - they have drawn quite a few - and - even with Zlatan - they failed to score many goals (without him, their goal-scoring record would have been truly execrable), but, Mr Mourinho's legendary luck notwithstanding, I don't see them finishing in the top four or five spots.
Both Liverpool and Manchester City had been somewhat erratic in recent weeks - and expecting them to win with any consistency - even with the dangling temptation of the possible prize of a place in the Champion's League - may be asking a little much.
