Bayer Leverkusen treble accomplishment shattered and they have to settle for two titles this season. The DFB-Pokal was important for Bayer Leverkussen after failing to win Atalanta in the Europa League final. They've been one the promising club this season with just a defeat. Xabi Alonso is currently the main instrument, he has helped his club deliver good news and will always do the pushing moves to making things running smoothly.
It was surprising to us all how Leverkusen ended up losing to Atlanta because with the way they have performed throughout the entire season no one expected them to lose to Atlanta. It could have been a treble for them but winning two trophies is not bad and they still had a wonderful season regardless.
Xabi Alonso is really doing a great job handling the team and he seemed like the main instrument just as you mentioned but the players are also have a very vital role in the success of the team so i feel it’s too early to conclude that Alonso is the key instrument. Let’s wait and see how it goes this coming season before we conclude if he is the mastermind behind the success story, and if he does maintain same momentum even after losing some players then he needs to applauded because i am confident that one or two players will leave the club anad more players will be added.
