I don't know how possible this will become looking at the current performance of Manchester United, they managed to defeat Rangers in their last Europa League match their performance doesn't look like they want to win any trophy this season so I don't seeing them getting to the Europa League semi finals I don't see that happening with this poor performance. Working harder to achieve a good result is possible but winning big teams there should be some level of seriousness and improvement in the team and if you look at the performance of the team they have got some unserious players who need to step up their game play so they their fans will keep supporting them to victory.
Manchester United's performance doesn't seem like this team is worthy of winning the title. Winning the Europa League title is not an easy task. Manchester United has won the last 4 matches of the Europa League. However, their opponents were quite weak. Even then, I don't think Manchester United dominated and won.
Manchester United's opponents in the knockout round of the Europa League will be quite strong. In the Premier League matches, we have seen that Manchester United's performance against strong teams is very weak. So I would say that if Manchester United's performance improves, they have a chance of winning the Europa League title, but if their recent performance continues, it is not possible for this team to win the Europa League title.
