contrary to this, it is unlikely that sevilla can afford any major signings with the clubs financial standing and yes, getting champions league football does not change that position. it is left to see if sevilla are able to get quality loan signings, else they would struggle with relegation like the just concluded season
It's difficult to fight in the Champions League when a team doesn't have high-quality players, but in the season that just finished Sevilla were still able to stay in the middle area of the final standings and it's not that close to relegation. But for next season Sevilla will have to fight even harder because they are already in a tougher competition apart from La Liga, because the Champions League is a league for the best teams from several domestic leagues.
This year will be a tougher year for Sevilla after winning the Europa League victory. They finished the league in the middle places and did not deserve to go to Europe. Just in this case, the trophy they won takes them to the champions league despite this ranking, and that's why they should get very good players in the transfer period.
