This is a bad move by Atalanta management, I don't think the team will be able to improve by hiring a coach without any successful experience in previous teams so I don't expect anything for Atalanta next season because I'm sure they won't be better because the coach they brought in doesn't guarantee anything from his past career history.
Straight 8 years with Atalanta is really a long time. under Gian Piero Gasperini Atalanta improved a lot, they come up with capability to break Milan-Juventus-Inter stronghold.
last season they achieved 3rd place and competed a lot. I really can't find any reason to appoint Ivan Jurić as the new manager. It really feels like a puzzler. If they want to challenge Serie A they should choose talented and experienced one except Ivan Jurić who displayed a 36% win rate at Torino. he could be kinda promising but not enough for elite level competition. If he is able to stabilize Atalanta's form, laying the odds could pay off, otherwise we could see another sack incident.
