I also watched the match since the match started but indeed, in my view Atalanta managed to have the better morale and mentality.So, when Atalanta had the ball and attacked, at least I thought Atalanta really had a chance to win until Lookman finally got his first goal. From then on, I saw Bayer Leverkusen seem to lose their motivation and ambition because perhaps, Bayer Leverkusen were under pressure so it was difficult to get a good mood in the final match of the Europa League. At least,that's the view and or judgment that I have, so Bayer Leverkusen really failed because Bayer Leverkusen was also unable to score a goal in that match.
They tried to score a goal as quickly as possible and they managed to get it in the 12th minute. The goal they were able to create made their mentality even better so they created a second goal in the 26th minute. The 2 goal advantage they held clearly allowed them to have the upper hand , they could be more calm in playing the game, even though Leverkusen tried to press and try to create goals, they always managed to break it.
This is the key to their success in this match. Apart from that, they are also aware that Leverkusen can always score goals before the end of the match, and they anticipate this by continuing to focus. And the third goal they scored in the 75th minute was the killer of the match, because it was very difficult for Leverkusen to catch the goal with only 15 minutes remaining. So the strategy that Atalanta implemented in this match went according to plan and it led them to victory.
