they can achieve great results considering the great result they have achieved is the result of years of preparation so as they have been able to do in recent years they will find excellent players who will be able to honor the shirt and do well in the coming years too, I still remember when Josep Ilicic was there who great player, it was thought that it would be difficult to find a player to replace him given the depression and yet he lost and the club was able to replace the player very well so I think they can achieve excellent results with excellent replacements
If what you mean is the Atalanta team, I also have no doubt that they will be much better than this season in the next season, but that doesn't just revolve around the best players, it also includes the tactics they have at the moment. they can develop it again in the next season. Because there are many people who didn't expect the tactics that Atalanta had this season that they were able to win the Europa League which was quite surprising because before that no one predicted they could win with conditions like that.
I also hope so, their success in the Europa League will spark their enthusiasm to perform better next season. This is clearly good capital for them to show that they can also compete. This season they even have 2 final matches, in the Europa League and in the Coppa Italia. Even though they failed in the Coppa Italia because they lost to Juventus, that was also an achievement for them, moreover, they were also able to pay for their defeat in the Coppa Italia by succeeding in becoming European League champions.
There are still many records they have to improve and they have to do it quickly, because if their performance is still like this season it will make it difficult for them to compete, however they have to improve their performance.
