Leverkusen seems to be interested in improving the midfield. The way they have actually performed, it feels like there is no room for improvement. But I heard that they are very interested in improving the defense. We could say that the defense is the main area that they could improve especially after looking at the Europa League final.

Anyway, it is good to see that they are also worried about the supply from the midfield to the attacking lineup. Maybe they are worried because they have scored a few goals less than Bayern Munich, and they want to absolutely be ready. By the way, this will also improve the depth of the squad.
