I disagree.
If Spurs get draws at Everton and Arsenal and lose to United, we'll be 1 point behind with 2 games left.
If Arsenal lose away to United, beat WBA at home and draw with Man City and Pompey away, we'll be 1 point ahead of them still.
Granted they can both pick up more points than that, but so can we. The above isn't unrealistic - we're still in there with a chance!
