This condition certainly led Atalanta to win the Europa League and is ready to add to the Italian quota that will play in the UCL. Leverkusen, on the other hand, ended their unbeaten streak this season and they certainly failed to win 3 trophies this season. They may still have a chance to win the DFB-Pokal against FC Kaiserslautern.
Surprises like this often happen when the favorite team is defeated it's just that we didn't expect Leverkusen not to score
Regardless of whether this is just luck for Atalanta what is certain is that 3 goals is the best achievement moreover this is the final match.
H2H from the previous two matches, of course Atalanta is superior. But many people, including me, think it's time for Leverkusen. The most basic consideration is that Leverkusen is unbeaten this season in the Bundesliga, while Atalanta is still struggling in Serie A to maintain 5th position so they can play in the UCL in the next season.
Yes, the match is over, and this is the condition on the field. One goal turns out to be difficult to get, let alone win the match.
everyone must be thinking as you are thinking, which is that this is an opportunity for Leverkusen to improve their meeting record with Atalanta and beat them in the final. As you said, one of our considerations for predicting like that or thinking like that is because we saw that Leverkusen was extraordinary this season and without experiencing defeat before meeting Atalanta, in the end it was Atalanta who managed to give them defeat this season.
This was Atalanta's success, because they didn't waste much time and were able to take the lead immediately after the match started. They know very well Leverkusen's strength this season and they implemented a strategy that Leverkusen could not anticipate. They also managed to silence key players from Leverkusen so they couldn't do much to give Leverkusen something in this match. Once again Leverkusen had to recognize Atalanta's superiority.
