Atalanta need to stop selling their important players like they sell Hojlund last season. They will play in Champions League next season, they will need to upgrade their squad depth to able to compete with top teams. Gasperini is a good tactician, he elevate Atalanta to be a tough team and have an attractive gameplay throughout his coaching career at Atalanta.
Despite they have won a european trophy, Atalanta still need to have improvements. They have capability to compete for the title race next season, if they are able to maintain their form with some improvements. Winning the Europa League trophy can become a morale booster for the players, I hope they will enter next season campaign with confidence and compete for Scudetto.
Atalanta is just an average team, they must be interested in a big offer. If there is a big offer to Lookman or other players, it seems hard to reject it. Moreover, Atalanta isn't a big team, the player must expect to move to a better team. If the offer comes from the big teams in EPL, or the big teams from other leagues, I think Atalanta players may consider leaving Atalanta.
