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.
Sevilla not have impressive performance last season and UEFA Champion League automatically ticket get after winning UEFA Europe League and finished on 12th standings placed in domestic league. Seems have the same scenario in this season for relegating to Europe League by finish on 3rd standings place. I don't optimistic with Sevilla have chance qualifying to next round although in group B not any strong opponent teams except Arsenal are guarantee will finish on 1st standings position.
In domestic league, Sevilla is the only one team can't get points yet until playing three matches and I don't sure with bad capital in domestic league have good achievement in UEFA Champion League.
