It is very difficult for Manchester United to get into the top 4 places. Considering the tough rivals in the Premier League along with the point difference, I think it would be better for the league to fight to get to the European league. They had some good games against the best teams in the league, but considering the poor performance in the UCL this year, it was not the year they wanted at all.

Manchester United will face major obstacles in making this happen. United's rivals, Tottenham and Aston Villa, should consistently fail to accumulate points. Tottenham is only 6 points ahead, united while Aston Villa is 9 points to the united. The main issue is that the remaining matches are becoming fewer, and it is extremely difficult for Manchester United to overtake Aston Villa and Tottenham considering fewer matches remaining make it even harder and mu potentially widen the gap.
I'm not sure if Manchester United will be able to get winstrea all of their remaining games. Manchester United must maintain a winning streak until the final match of the EPL because it is their only chance of finishing in the top four.
Tottenham and Aston Villa can also perform better in late-season competitions, which will make MU get into the top . Manchester United has no chance of qualifying for the UCL if Tottenham and Aston Villa continue to perform well. This is one of Manchester United's biggest obstacles.
Ten Hag may be fired soon if he is unable to help Manchester United get into the top four.
