Next season will be a more difficult season for Atalanta. They will play in the Champions League which is more competitive than Serie A or UEL. Atalanta needs to add several players to the depth of their squad. The current team is very good and they are the champion team because they managed to win the UEFA European League trophy. But that won't be enough for them to compete in the UCL. This reminds me of Leicester City in the 2017/2018 season when they played in the UCL. They must not sell their important players and they must look for some new players.
Next season is not going to be an easy one because we've watched how these clubs becomes interesting and going all in when it comes to major titles. Atalanta are Europa League champions and they have one main goal to ensure to reach significant phases in the UEFA Champions League next season. This club we're talking have been underrated several times but they never bend their head from accomplishing main titles, consistency matters and got them this far.
