Xabi Alonso has become a very special manager for Leverkusen fans already. It is easily visible. It was such a cool thing to see Xabi Alonso lifting the trophy with the fans at the stadium. He climbed to the tribune to do that. 
He is about to break every record available as it seems. First of all, he started with making Leverkusen the first ever undefeated champion in the Bundesliga history. Now he is going for finishing the season with 3 titles by not losing any game as well. This must also be some kind of a record. I don't believe there is any better achievement earned than this by another team so far. I don't remember any manager who started their career this spectacular.
