The win over Liverpool have made them gaining a confidence booster, and since then, they have a great consistency in the league. Leverkusen is consistent at not losing games, but they were having draws in last some games. Considering all these, I think Leverkusen and Atalanta share a fair chance to win the trophy, but just Leverkusen is a bit more favorite due to their this season records.
I admit that Leverkusen are in top form and have performed very consistently which marks a great season, even better than Atalanta in certain aspects. However, Atalanta should not be ignored either. Although they were beaten by Juventus after their impressive winning streak, this clearly showed their strength but also their resilience to come back. Atalanta's win against Liverpool did boost their confidence and showed their ability to compete with top teams, but the consistency they showed made them a strong contender in the league and thus continued to survive.
While Leverkusen may be favored based on their season form, Atalanta's improved form, especially in high-stakes encounters puts them ahead in terms of victory. Both teams are equally capable and have the potential to become winners, therefore we anticipate an interesting and even balanced match.
