What bayern Leverkusen has achieve is something that is unbelievable and it's going to take a whole lot of hard work for them to actually replicate this kind of performance again next season and that's where the entire team should be focus on now not that one final defeat to Atlanta, of which everyone understood is a final and never really expected Atlanta to hand the title over just like that without a fight.
Exactly what I think aswell, it was never a game that promise to be easy and Leverkusen should have never taught they were going to be handed the trophy just like that, they had all the odds in their favour but they still needed to show how well they were deserving of the trophy by winning that particular game and that's why it's never a good idea to underestimate any team especially if they have gotten to the finals.
Atlanta winning Liverpool at some point in the league was supposed to be a lesson to Leverkusen not to have it lightly will with them because they were looking like they will not cease to utilize every privilege and opportunity they have got if they eventually get one just like they did against Liverpool even with the whole strength exhibited by Liverpool then in the Europa and their domestic league aswell, Leverkusen had a tough task ahead but it appears they weren't ready for it and so they lost the game to Atlanta who then became the winners of the league title.
One thing I've got to understand is that for a team to have been able to get to a finals of any game, they are definitely not to be underestimated because they have actually thrived enough to be able to have made it to that point and so they should be taken seriously even if they look in experienced with a finals of a particular league game, they still shouldn't be seen as a team that cannot win the game became at that point they will put in their very best and make sure they win if the opportunity comes.
