We have distance like this in many leagues as this can happen to any team like we have in past by Bayern Munich and then PSG and in last year we have Napoli which was once having 17 points difference and then now in current season mostly teams are doing good competitive performance but as described PSV is playing completely in another level which is giving them good edge just after 16 rounds.
Currently, no doubt having this distance here in Bundesliga between these two teams is nothing and Bayern Munich is also having good ability to fight back without any problem but right now as we have consistency in Bayer Leverkusen is also impressive and things have never been challenging hopefully, we will have good end of this season.
This season's battle will belong to Leverkusen and Munich. both of them will dominate this season and Leverkusen's consistency this season is of concern to many Bundesliga fans.
16 matches without defeat, how can Xabi Alonso have a very strong team like that? There should be rumors that Madrid has made him one of the candidates for their coach because their main coach is currently rumored to be leaving Madrid.
