Regardless of your belief in Newcastle who will finish in third or fourth place, I am more inclined to see the possibility of Man United finishing third, based on analysis of the remaining matches and facing a stronger club. It is possible that Eriksen and Casimero will be able to play in the next few matches, so that the strength of Man United's midfield has improved, although it is not yet clear to Eriksen when he will return to strengthen Man United after undergoing injury recovery.
I agree with you on this one, Newcastle games has been a glorious outcome in their few played matches, their come back on the top 3 is a very condeble job but I think they need to push hard even though they are ahead of Manchester United, other teams will be having this phobia anytime they have match with them, I never even expect them to quicly climb back at the standing of top 4.
For Liverpool it seems difficult to reach the top four or five positions in the standings and it is very unlikely to finish there. Tottenham still has a great chance of finishing in the top five or four, because the point difference is currently not far from Man United and Newcastle, even though Tottenham has one game more than them.
I think Liverpool already miss the chances when they played against Chelsea, they should have win the match to stablized their points, now they have their next match against Arsenal, and the way Aresenal is in form, they may trash and humiliate Liverpool again in Anfield and I don't think they will be able to sustain their standing, Fulham may overtake them because they have higher winning rate in thier next match than Liverpool and Brentford.
