I can say that they surprised me a lot in yesterday's match. I thought they would perform much better, they almost lost the match. They managed to rectify the situation at the last minute. Of course, what matters is who wins at the end of the match. It is expected that a team that has not lost a match for a long time will play much better against a weak team. They will pass the round without any difficulties in the next match, but we always have the chance to see surprising results.
If they were playing like this in the league, their rankings would be different

Against a club that is quite far below them, Leverkusen are more confident but that is precisely what makes them lose momentum and not play well, especially in defense.
Leverkusen were too engrossed in their offense which backfired because in the end their opponents could create some good chances on the counterattack but in this case I don't think it will be a big problem for Leverkusen.
Indeed even if it's a draw they certainly have a loss but for Leg 2 I think they know what they have to do because their chances remain big in the Europa League and Xabi is still maintaining his unbeaten record.
Now Leverkusen must try some new alternatives so that the players do not continue to be suspended because after all, now they have to prepare again to face Wolfsburg in the Bundesliga and they cannot let the same incident in the Europa League happen again in this competition because it could destabilize them.
