I will not agree that Liverpool and Leverkusen are stronger than Atalanta, and that it was because of the players great enthusiasm that made them to win these two clubs 3-0 each. All these clubs are playing in various leagues and they have their different tactics, which it is the one with the best tactics that can outsmart the other club that will win the game. Atalanta was stronger than both Liverpool and Leverkusen due to their game tactics. Atalanta was able to seal up their defense and uses counter to penetrate their opponents defense. One thing that surprises me is that they don't always miss a good one on one. It shows that they have professional strikers.
When a team played in the Champions League and also the European League, of course we can't compare them better than other teams, Atlanta passage to the final is actually quite surprising to all of us regardless of the quality and also the value of the squad they have compared to Liverpool, but indeed in football apart from the quality of the team, of course the strength of a team is not only determined by tactics, But also by experience, mentality, team cohesion, and the ability to execute game plans well, so that it can make the team chances of winning greater than just a team that only has the quality of their squad.
In the final match, of course Leverkusen was the favorite to win considering that at that time Leverkusen was in an unbeaten condition throughout the season and indirectly of course it motivated Atlanta to be able to be the first team to beat Leverkusen this season, in my opinion, defense is the main factor for Atlanta to be able to beat Leverkusen in the match, because I see that Leverkusen attack was not able to penetrate the 3-defender scheme applied by Gasperini in the final match.
