Last season there were several big names such as Milan and Liverpool, who usually play more often in the Champions League, they had to play in the Europa League, which made many people interested in watching every match and thought the winner was one of the elite clubs. But the surprising fact is that the club that was not the favorite was able to win the UEL title, even so I think the Europa League is no less prestigious than the Champions League.
And next season there will also be several big names such as Manchester United, Roma and Tottenham but I am no longer predicting too early for fear of making the wrong target again

and there are also no clubs who have been relegated from the Champions League which of course will make the competition even fiercer.
Actually, it wouldn't be wrong to make predictions now even though it still looks quite early and no league has started yet because in the Champions League there will also be elite teams who will enter the European League next season. However, from the names of several teams that you have mentioned, you can actually give a little idea that next season's European League will still be a league that is quite fierce in terms of competition, so there will also be quite a lot of spectators.
A complete season ended a few days ago and we all know what the results were last season. At the end of the last season, every team participated in the Euro and Copa America, so club level games are suspended for now, but club level games will be held again very soon. This season in the Europa League we will see several new teams with Manchester United being the most prominent. United are naturally considered favorites in the Europa League this season.
Manchester United is quite old and big team compared to other European League teams, so the European League spotlight will definitely be on Manchester United. But only considering the statistics will not mean that Manchester United must perform well but Manchester United can do well in the Europa League.
