Sevilla is not a strong team to play well in the Champions League. They are fortunate to have won the Europa League and qualified for the Champions League. In La Liga, this team was at the 12th position in the points table. If they did not win the Europa League title, they could not qualify for the Champions League. Their performance in La Liga was very poor. And this season also in La League we are seeing poor performance of this team. I don't think they can do well in the Champions League. I doubt the team will win even one match.
Everyone is fortunate when they win a big title, but that doesn't mean they have also been lucky. If you look at the whole Europa League season 22/23, don't you think that Sevilla was by far the best team? Discussions aside about a possible penalty against them when they played Roma in the final, but they have eliminated some of the biggest teams in the Europa League and their game in that competition was totally different from what they played in La Liga.
While I think that a surprise like that could be possible in the Europa League, I don't think that Sevilla can eliminate the best Champions League participants. But I would also not underestimate them as we have seen the result from teams underestimating them in the Europa League. Juventus and Manchester both thought that they should be safe to beat them.
