I think Bayer Leverkusen has great chance of winning three big titles this season. They have been playing very well and have not lost game which shows how good they are. Their manager Xabi Alonso has done great job and he is the biggest reason of their win we can say and they are focused on winning biggest prizes. They are one of the best teams in Europe right now and if they keep playing well and working together they might just win all three titles. It won't be easy but they have a good chance and if they will focus so they everything is possible.
This opportunity is clearly visible when Leverkusen continues to win game after game in the Bundesliga even though they have ensured the title is in their hands. Meaning Leverkusen has a strong ambition not to make mistakes and does not want to experience defeat and the Treble Winners are their priority this season after achieving consecutive wins and have creating an unbeaten record for one season. Xabi Alonso is clearly the best manager at the moment because he is the only coach who is able to lead the club to achieve treble winners without losing, just play the next 2 matches and Leverkusen will celebrate their victory this season.
Xabi Alonso achieved this record at a very young age (as a coach), it is very difficult for other coaches to lead his team to end the season without even losing in the domestic league. As a result of his expertise in building Leverkusen from a team that was never considered in the Bundesliga to a team that has a winning mentality, it has attracted interest from other clubs to bring him in. He chose to stay in Leverkusen because he didn't want to just leave the project he had just built.
It didn't take long for Alonso to make Leverkusen a tough competitor for Bayern Munich, his cool hands have made Leverkusen create new history that has never been achieved before, he is also trying to make Leverkusen win its first Treble winner in the club's history.
