Man Utd major priority now is to give top 4 spot a shot, now that they are out of this season UCL, they only have the league matches to play and I believe they will like to fight till last day of the season, but it's very unfortunate that their current standing on the table is not favorable because of consistent performance of Arsenal and Tottenham who are the likely contenders for the spot, at the end of the season Man Utd will likely qualify for Europa league, as it is now Arsenal would give room for any flop that can warrant or stop their top 4 spot.
Manchester United can still fight for their slot into top four, but problem is no one know what's going on and why are they not producing better results which was expected few weeks back now all top ranked players are not giving their best and manager is also clueless so with this all we have very few chances for having them into last four specially with now Tottenham and Arsenal both having some good advantage with their performance and quality fixtures are also favoring them.
If from here Manchester United have top fourth slot then surely for me, it's going to be the biggest miracle of this decade because right now I have feeling they are not going to do this but as we all know any result is possible in soccer all things can happen and specially when you have few legendary players in your squad they can change things very quickly.
