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.
Only 3 points behind and what they can do is win the remaining games, if they can't win, at least they have to be able to get draw, I sure Roma will try to get win and catch Atalanta.
Even though if they manage to qualify and enter the UCL, they won't last long or it could be said that they might just be eliminated sooner, but at least Atalanta has proven that they are strong enough team and are able to compete in UCL group stage.
For the European League itself, I would not expect anything from Atalanta to win the final match, the opponent is Leverkusen and this is team that has not been defeated, it is impossible for Atalanta to win this match.
