It would be a shame if Leverkusen unbeaten record ended at the hands of Qarabag, if this really happened then this would be the first defeat they have received so far. I am very curious about how Xabi Alonso got out of the pressure in the second half, and of course the intensity of Leverkusen attacks will increase in the second half because they want 2 goals. If Leverkusen loses, their chance to qualify for the next round is still open, because in the second leg Leverkusen will act as hosts at BayArena.
Maintaining an unbeaten record is not always something a club can maintain. If the current situation is that Bayern Leverkusen has lost by 2 goals and the score cannot be equalized until the referee ends the match, then Xabi Alonso is forced to accept that his record of never being beaten so far ends in the hands of Qarabag FX. With the time available now and as is their habit in every match, maybe they can equalize the 2 goals they are currently behind.
It is not always easy to maintain an unbeaten record especially for teams that have most of their star players in the first team and the major reason why Leverkusen is losing this team with the number of goals is because the coach tried to rest most of his key players to try the players from the second eleven and it didn't turn out well for him tonight as they are two goals down at the moment. They may finally lose the game tonight and their unbeaten record is all competition be broken but they will have more concentration on the German league which they currently dominate.
