They are FAR from odds-on to finish Top 4, regardless of their results so far this season the way they are performing, and escaping by the skin of their teeth many times, must have alarm bells ringing at OT.
At the moment I'd rate their chances not much better than ours except that we are now looking far more like the stylish, successful, team of last season (though EL football may change that for the worse for us). Arsenal have by far the easiest run-in (only 1 game remaining of their matches against the Top 7) and Southampton too have an easy final ⅓ of the season with no encumbrances and just a couple against the Top 7. In terms of difficulty it goes : Arsenal > Southampton > United > Liverpool & Spurs equal.
