Yes that is right Bayern Leverkusen long undefeated streak shows how strong and determined they are. Even though they lost in final but it is clear that they are good team. And exactly hey can play well against tough opponents and have good chance of doing well in Champions League. Champions League has many strong teams but Leverkusen has already shown they can compete with the best in the Bundesliga. They might not win first place but I think they'll come close and do well in the competition. Their team work can help to stand against the tough teams and they already showed it.
I hope Leverkusen can achieve more than they have won this season, defeat in the Europa League Final disappointed everyone involved in Leverkusen. Due to a small mistake when facing Atalanta, they failed to win the first Treble Winner in its history. Next season Leverkusen will play in the Champions League, they must be better prepared and need to develop their strength to face bigger challenges. They may be able to maintain their dominance in the Bundesliga, but there is no guarantee of success in the Champions League because the level of competition there is more competitive than in any other tournament.
I think it was not because of a mistake that Atalanta beat Bayern Leverkusen in the Europa League finals. Before the Europa League finals, Atlanta was in amazing form, which helped Atalanta be in a better position to beat Bayern Leverkusen in the Europa League finals. And if it was a mistake that made Atalanta beat Bayern Leverkusen, the score of the Europa League finals would have been 1-0 or 2-1. The UEFA Champions League competition is a different competition from the Bundesliga. Bayern Leverkusen needs to be at their best performance if they want to qualify for the round of 16 because they will be playing against the best clubs from other European Leagues.
