Some small teams are quite likely to make surprises in the Europa League. It has always been like this but it happens until a point. I can't say Qarabag have much chance to move on from now on. I must appreciate their fighter character against Braga. That amazing effort resulted in achieving a big victory at the end.
But is there anyone who really thinks Qarabag can do the same against Leverkusen? The best I can expect from Qarabag is to show some resistance home in the first leg.
But Leverkusen are just one of the biggest title contenders here. No way they are saying goodbye in this round.

Leverkusen is truly unbeatable at the moment. In the Bundesliga, Leverkusen has not lost so far. Even though the season has reached the middle and 23 matches have been played there. Bayern even recently lost to Leverkusen. So in my opinion the small teams in the European League will not be able to stop Leverkusen. So I am sure Leverkusen will qualify for the next stage in the European League. And next season, maybe Leverkusen will be a strong challenger in the Champions League.
Sometimes, it is still possible for big teams or favorite teams to get unlucky results when they play against mediocre teams . But regarding Bayer Leverkusen this season, the reality is that Bayer Leverkusen has always managed to consistently produce good results, whether with 3 points or only 1 point . But yes, basically Bayer Leverkusen remains unbeaten so far this season, when playing against big teams and also when playing against mediocre teams. With considerations like that, of course Bayer Leverkusen will still have the ability to remain consistent and play well even though the opponent they will face is Qarabag. So, I think the miracle is not for Qarabag, but for Bayer Leverkusen because Bayer Leverkusen remained unbeaten and that is also a miracle.
