If Manchester United cannot win this cup, this season will be a very unsuccessful season, and they are aware of that. That's why they will do whatever it takes to be successful in Europe.
Maybe their current target in the EPL is just not relegated. They are trying to keep getting points without big targets. Then they focus on the Europa League. Maybe realistically the Europa League still has many different opportunities than the EPL. After this season ends, maybe Amorim will make a lot of big changes. Amorim may take advantage of the transfer market to add strength next season. It looks like they will suffer the same fate as Arsenal or Chelsea are in the bottom of the table. Against Nothingham is realistically maybe 1 point to take home.
Manchester United they are looking towards the europa league if something good come out this season but the Europa league games is another difficult game for Manchester United because their are other teams hoping to get the title. Manchester United performance this season is very bad and I'm not very sure if it will be possible for them to win Europa league this season. The performance of Manchester United this season is so poor, the coach needs to get better players for next season.
This is football, don't rule out the possibility of anything happening, the clubs still remaining at the Europa league are clubs Manchester united can also withstand, regardless of how bad you think they've performed lately. The Manchester United team have brilliant footballers, what the team needs are key players that will stand as catalyst from the defence, the midfield and their attack, ordinarily they have young players that could do the running and the passes, they just need some players who are experience and formidable, just the way Real Madrid where able select Alexander Arnold, because they know how experience he is and how of a strong catalyst he can be on the Central midfield since Modric will soon be leaving.
