And regarding Lookman, I think if he leaves Atalanta, it will indeed weaken Atalanta. And in my personal opinion, Atalanta will even struggle to secure a Europa League spot if they sell a key player like Lookman.
Atalanta after many successful seasons will face with a first challenging season by losing the head coach and many star players. Atalanta need to work hard in order to repeat success like Sevilla did in many years. Detecting young and unknown players then selling them for money and replacing them with new players while still maintaining very good quality in many years.
Atalanta have no other choices than relying on their scout team in order to bring good new players who potentially can grow up and become new Lookman, Rettegui and more. Losing Gasperini is very challenging for Atalanta and it is like they will have to replace many important people in the club within a short summer season.
Yes, of course, with Atalanta's current situation, they will certainly struggle next season. What will make things even more difficult for Atalanta is that they will have a very busy match schedule next season. This is because Atalanta will also be participating in the UCL next season, which will undoubtedly disrupt the Atalanta players' focus. Playing in more than two competitions will undoubtedly drain the players' stamina and mentality. Therefore, Atalanta will likely slump next season if they can't address their problems now.

Furthermore, Atalanta has only brought in three new players. The other three were loaned out and eventually signed by Atalanta. So, considering this, Atalanta has only brought in three new players Kamaldeen Sulemana, Marco, and Honest Ahanort. I believe these three new players will likely not be able to fill the void left by Atalanta's key players. So, given this, I think Atalanta really needs to bring in new players, especially for the attack. Because if their attack is bad, I think Atalanta will really be facing big problems.
