They have definitely found their way back into higher quality soccer that they are usually able to play. The beginning of the season was a horror for them and if you have a start like that the confidence is also starting to shrink from one game to the next.
Yes, thankfully they found their way back so well that they seem to be able to make an epic comeback before it's too late. And of course they won the European league, isn't this a pretty drastic progress for them. However, next season is always waiting, whether they can really rise and become big again or not, because of course there will be many more challenges. And they have to find good players again who are suitable to be able to rise.
In the previous seasons, they actually played quite well, it's just that this season they were very hampered by conditions where they were very difficult in the domestic league, but now there's no need to think about that anymore, it seems because they really did their best and qualified for the Champions League again. League again at the same time makes La Liga have 5 slots this season after last season was the bundesliga in the Champions League.
After all, in the end Sevilla will always return to the Europa League. Yes indeed, Sevilla this season won the Europa League title and of course, this will make Sevilla play in the Champions League next season. But in the end, Sevilla will not be able to advance to the last 16 in the Champions League and Sevilla can only be in 3rd place in the final standings in the Champions League group stage. That way, Sevilla will play again in the Europa League and have a good chance to win the Europa League title. So, it seems, this is still happening for Sevilla from season to season.
