Leverkusen has in my opinion a vital 4 points ahead Bayern and this points might make the difference and decide the champions of Bundesliga this season. I also feel like Leverkusen is playing the best football in Bundesliga and without Xavi Alonso none of this would have been possible.
I guess its to early and with that only 4 points ahead to say that Leverkusen will be the Champions of the German League or win the title this season.
There are so much games to play and there can be so much happen till to the end of the season.
But yes for now it looks like that way that Leverkusen have the best year ever and maybe win it , but other teams dosnt sleep.
