What happened in the Europa League final this season is proof that mentality is quite important, a landslide victory is not a matter of luck but rather a feat of worthiness.
In terms of quality, Atalanta is not better than Leverkusen, but Atalanta's team mentality is much stronger than Leverkusen, which has just built its team, especially since Xabi Alonso is also a coach who is still quite young and less experienced.
In the Europa League and Champions League I think the atmosphere is the same, this is a big European competition which of course will be very fierce. The difference is that in the CL the best European teams are there which makes of course the competition will be much fiercer.
The Europa League final was an exciting match and both teams have shown how their mentality, performance and also their desire to win the match, Leverkusen so far has a very strong mentality and they have been able to prove how they can make a comeback in every match they have faced so far, while Atlanta, of course we cannot underestimate their unyielding attitude even though facing a team that is currently in sufficient condition Excellent and also undefeated in the various competitions they participated in, Atlanta, which is very underrated this season, was actually able to become the first European team to manage to beat Leverkusen as well as break their unbeaten record this season.
I think Atlanta victory over Leverkusen was not a lucky one, but it was the result of hard work, careful preparation, and of course a champion mentality, besides that of course the strategy and also the game scheme they applied in the match was really effective in destroying Leverkusen game which was quite strong.
