It's not just you who think like this, but almost everyone will also think like that, because what they did this season was truly extraordinary and it attracted a lot of attention to them. Now many people are waiting and want to see how Leverkusen will perform in the Champions League next season, whether they will perform well or vice versa. This is something we usually see if there is a team that usually performs normally but this season performs extraordinary, that will make them get a lot of attention.
Not only them actually, Girona will also receive greater attention than usual after they managed to get to 3rd place in the La Liga standings, which is very difficult to get there. However, there will be differences from Leverkusen and Girona, because Leverkusen finished the season without defeat in the Bundesliga and they only had 1 defeat in all the matches they played this season. So attention to them will be much greater.
I would guess that Girona situation will be a little sensitive. Because they had one good season so far, that's it. Meaning that they are going to end up with a situation that is going to be quite tough, and I am not sure if we are going to face the same thing again and again. We should probably have some changes in some places, and for that to work, we need to make sure that we are dealing with a good thing and not having any issues.
This could be done with Girona keep getting good players like they did, so they could continue to be good, but that's about it, I do not think that it will be simple. We need to just see Gironas transfer period before we can decide, but I feel like they will probably not be as good this year.
