Manchester United's overall performance in the Europa League has been quite good so far. Despite their poor performance in the Premier League, Manchester United has been able to do well in the Europa League. Manchester United are undefeated in the Europa League so far. However, Manchester United have drawn three matches. If Manchester United's performance improves, they definitely have the potential to dominate the Europa League.
However, Lazio and Athletic Bilbao's performance is the strongest on the Europa League platform. Anderlecht has also been able to perform well in the Europa League. I did not know Anderlecht. I was very surprised to see this team's good performance in this year's Europa League.
Manchester United are unbeaten in the Europa League even though they have suffered three draws which made them lose points to place the top position. Amorim seems to be prioritizing the Europa League trophy because if you look at the performance in the Premier League it will be difficult for them to catch up on the points so that the opportunity to qualify for the Champions League is only through the Europa League if they are able to emerge as champions.
Lazio and Athletic Bilbao will be strong challengers for any team because even though this is the group stage they have performed more consistently. We'll see how things pan out after the group stage is over to see if Lazio and Athletic Bilbao can make it to the semi-finals.
