If Liverpool hits form - and it's looking a bit like they are - it would certainly be no sensation if they win all of their remaining games. They have the easiest run-in of any team, there are no games where you wouldn't reasonably expect them win, each game seen in isolation.
That would bring them to 71 points. The question however is if that is likely to be enough. I don't think so. I think United and Newcastle both have a pretty good chance of reaching 75, and a very good chance of reaching at least 72.
For instance, we could lose to both Spurs and Brighton and draw at home to Villa, and still get to 75. Our other remaining games aren't any worse than what Liverpool's facing. Slightly tougher for Newcastle since they have one less game to do it in, but they could drop 5 points against Arsenal and Brighton and still get there if they win their remaining five, all against bottom-half clubs.
I agree about Spurs. They'e on 71 if they win all of their remaining six games, but those include us at home and Liverpool and Villa away. That'd be some turnaround......
The way the probabilities stand right now, I don't think it's really a top 4 race until United or Newcastle slips up somewhere they can't afford to, and Liverpool still hasn't dropped points by the time that happens.
Instead, it's really a tight race for the two EL spots between Liverpool, Spurs and Brighton, with Villa the dark horse. But they have a pretty tough run-in, with Man Utd, Liverpool, Spurs and Brighton among their final six.
