I agree that their performance has shown a decline, but I think this is a very natural thing because they have confirmed themselves as Bundesliga champions this season. So they don't have any pressure to play as usual, because the match results don't affect them in the slightest. It's just that if they don't lose then they will extend their unbeaten record, and in my opinion that is Leverkusen's only motivation in their remaining matches in the Bundesliga.

It's also fair to say that they got lucky when they were able to score a goal in the final minutes of the match, so that prevented them from losing. But actually they usually do that during this season, they can always catch up so they don't lose and they can even turn things around in several matches. This is the most extraordinary thing from Leverkusen this season and honestly we can't deny that.
