It won't be easy for Sevilla to at least get out of the group stage, but they still have plenty of time to improve the squad they currently have. IN La Liga this season they haven't played as well as they did in the previous season, but when in the Europa League they are like a different club, I don't know the exact reason why they can be different in two different competitions.
This is okay and I don’t see any big deal in them playing differently in these competitions, they’re prioritise in everything and they just prioritise the Europa League more than the La Liga they play in. This maybe because of the money involved, but I’m not sure it is. I just feel it’s better to put all your strength in what you think is achievable than the one that is not.
The Champions League is one of the goals for the big clubs to be in, and Sevilla has a place there, it's an achievement for them. They now have the nickname of a specialist Europa League club, I hope they are even more motivated to go beyond that nickname and prove themselves in the Champions League.
Qualifying to the champions league is a big achievement for them and they need to go extra effort in order to go far in the competition. This is not Europa League and it’s more competitive than the Europa League because of the big teams involved. If they can’t make it out of the group stage alive, at least we should see them in the Europa League next season after the group stage.
