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.
