The competition between these two teams looks very tight, just like last season where Bayern Munich and Leverkusen fought for the Bundesliga title. Bayern Munich must perform consistently if they do not want to lose their first position, while Leverkusen also tries to continue to put pressure on Bayern Munich. Their meeting later might determine their results. If Leverkusen wins against Bayern Munich, their points difference will be closer and they have the opportunity to defend their title for the second time.
I actually want to believe that Bayern Munich knew it much earlier before now that they are going to have Leverkusen as their biggest rival and contender for the trophy this season so making sure they are going to be able to stay ahead of them was one thing that was supposed and going to be their priority this season and now the the distance has been closed to the point is just four point difference is some how disturbing but then Munich still have the chance to still staying ahead.
Bayer Leverkusen has a difficult match ahead of them, Borussia Dortmund away. If they lose points in Borussia Dortmund away, Bayern Munich's job will be much easier. Because Bayern Munich will probably beat Mönchengladbach and earn three points. If Bayer Leverkusen loses points in Dortmund, the point difference between them will increase to seven points. From now on, Bayern Munich will not lose the lead. Bayern Munich still has the big advantage.
