In fact Sevilla have failed and slumped from last season but yes, last season Sevilla were still lucky to win the Europa League title so Sevilla got a Champions League ticket. But this season, Sevilla was really devastated because they were not successful in Europe and also, Sevilla failed to finish in the top zone in the La Liga table. Although indeed, there is still a second half of the season but obviously, considering the results that Sevilla has had so far this season, then Sevilla is just trying not to be relegated and that is Sevilla's main priority at this moment.
If you look at Sevilla this season, of course their performance in Laliga is almost the same as last season because Sevilla in the previous season also worked to avoid the relegation zone and this season they must also do the same. I think Sevilla is no longer a strong enough team in Laliga because they didn't make any good changes in the transfer window so they could easily be beaten by their opponents. On the other hand of course Sevilla for next season they will not compete in the European league and in the champions league and that is all quite a bad setback for their performance.
In today match, Sevilla had to surrender to Alaves where the final result of today match was 2-3 in favor of Alaves. Sevilla is temporarily ranked 16th and it is possible that they will fall into the relegation zone because the teams below them have not played their 20th match this week. Sevilla performance was really bad, they had to give up at home to Alaves.
Sevilla's performance in the last 2 seasons did look bad in La Liga but fortunately their performance in the European league was quite impressive and they managed to win the European league title, but this season Sevilla did not play in the European league and their performance in La Liga has not improved and is getting worse so It's only natural that Sevilla won't qualify for the Champions League and won't be able to compete in the European League knowing that their condition is much worse than before, so it feels difficult to be in the top 5 if their condition doesn't improve this season.
Sevilla lost to Alaves at home and this defeat is certainly quite embarrassing and Sevilla has made their fans disappointed and angry at seeing this defeat, Sevilla must immediately fix what is wrong with their condition so that they don't continue to decline, this season they must improve their position so that it is safe and not degraded.
