Sevilla does well at this competition, but at the same time they have been consistently at "around" the top at la liga so far, and yet last few years hasn't been like that for them, hence why there are issues. You have to realize, being top six in la liga on/off for 20 years does make a team very good, so that would be understandable and nothing changes.
However, we need to remember also that for past two seasons they have done quite bad compared to the past. Could they recover? of course they can, they have done much worse before and recovered, so I think they will be a good team once again in the future and should not face issues, they just need a couple seasons and they are going to be back at top 10 easily and then top six and just win this competition again.
Sevilla is the best teams won 7 Europe League tittle but their performance recently decreasing and this season failed reach the Europe League spot standings position. Have been two consectives season for Sevilla failed reach the Europe League spot standings position and I don't sure for next season have quit well performance behind still get financial problem issues.
Sergio Ramos had official announcement leaving Sevilla for next season and seems difficult will reach the top sixth standings place for qualifying to Europe League.
Next season, Manchester United must be one favorite team for winning Europe League trophy after their failure in this season in Champion League group phase and can't qualified to Europe League bottom finish standings position.
Get benefit after winning FA Cup make United get participants in Europe League although their position outside from Europe League spot place after finishing on 8th standings position.
