Usually Sevilla will only be able to finish in third place in the group stage in the Champions League and thus, Sevilla will return to play in the Europa League. But yes, if in the Champions League next season Sevilla are able to finish in first or second position, then of course Sevilla will continue to the last 16 in the Champions League. But, because so far even though Sevilla has managed to get a ticket to play in the Champions League, the reality is that Sevilla ends it more often in the Europa League and this happens very often or is experienced by Sevilla very often.
Sevilla's success in securing a Champions League ticket for next season clearly received high appreciation regardless of the drama of the referee who presided over the match. Sevilla holds an unbeaten record in every Europa League final in 7 finals, that's something really incredible about them so far.
I know Sevilla won't be favorites for the Champions League let alone reaching the quarter-finals, but they can make the most of their best chance of winning the Europa League despite only playing in the Champions League group stages. But habits like this must be changed because Sevilla can also give their best in the title race.
