You are completely right about that, because in the Bundesliga they showed a very high level of football, but clearly it is as you say, after beating Atalanata, it was like when you are on a cloud and you suddenly fall knowing that real life is different because that is where you step on the ground, and if this happened in the Europa League, in the UCL the level is much higher, it is superior, only the best in the world enter the UCL, so Leverkusen's preparation now must be much higher, just thinking that they can face the PL teams where their physical level is very demanding, well they have to be at that level to resist.
