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.
Apart from not needing to throw away the old players that Atalanta already has this season, the Atalanta team itself also needs to look at other players who are much better if they have enough funds to buy new players so they can be included in the existing squad. I am also starting to be impressed with the gameplay created by Gasperini because this was very visible when Atalanta played in the Europa League this season and also in Serie A this season. Hopefully next season things like that can continue with Atalanta so that other teams don't think of them as a weak team.
