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. 
In their history no coach have achieved this so it’s easier for the fans to see him as a special person despite only spending one season with the team. Everything they achieved was fully deserved, they worked for it and i think this season will be their best season in a long while. Congratulations to Bayern Leverkusen once again. 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. 
Nothing seem to be going wrong for them at moment and to see them not achieve this records seems impossible because i still wonder which team will be able to defeat them at the moment after they have turned around 2 goals against several times this season. It could have been different if they were to play in the champions league and they would have found it difficult to win all matches and remain unbeaten but a record is a record.
