If Gasperini leaves at the end of the season it will be a test of strength for Atalanta that have been punching above their weight for a long time now. Gasperini deserves credit (I don't want him here) but also Percassi and the rest of the management.
Calling Inter an aging squad is a bit harsh, they have a nice mixture in their squad although they could perhaps look for some younger opportunities. Acerbi will be difficult to replace but a lot of the really old players they should look to transition out one by one to keep the core fairly stable and have some continuity as well as build on the internal culture. Will be interesting to see what Marotta does in the summer because the ones to pick up the torch looks unlikely to do so (Frattesi, Asslani, etc).
