Next year, 5 teams from Italy will go to the UCL and Atalanta is still one of these five teams. Finishing fourth will not give them any extra profit. The point gap with Roma is not easily closed, so we can say that Atalanta will be in the UCL next year, of course, if they can fully qualify. They were upset after the final they lost to Juventus, but they are still pushing for the top positions in the rankings by winning 3 points in Lecce.
Yes, Serie A is one of the leagues that has 5 places for teams that will play in the UCL next season and of course this makes Serie A pretty good league, the rapid development means that Serie A can have this good opportunity next season.
Atalanta is currently the caretaker for the 5 teams that will have the opportunity to take part in the UCL competition next season and of course they can compete with other strong team in the UCL if they really maintain their position.
Victory over Lecce has also provided very good opportunity for Atalanta, moreover in the last match Atalanta was guaranteed to win over Torino and they could comfortably finish as team in 5th place.
But there is postponed match which is quite worrying, namely against Fiorentina and this is the only match that can put pressure on Atalanta.
As much as possible, Atalanta must maximize the remaining matches in order to secure tickets to the Champions League. Of course, this opportunity is now within his grasp because UEFA has given five slots to teams in Serie A. However, Atalanta seems to have enough to win one more match to avoid being chased by Roma. Apart from that, Atalanta also has the opportunity to qualify directly for the Champions League if they are able to win the Europa League title, but this step is also very difficult because their opponent is Bayer Leverkusen. But I feel quite confident that Atalanta will advance to the Champions League through the fifth slot in the Serie A standings.
