If Leverkusen can be able to hold on and get a point against Munich, then they can go the complete season unbeaten, and their chance of winning of getting point against Bayern Munich is high because they collected four points against Bayern Munich last season.
That will definitely be Leverkusen's next target against Bayern Munich and in fact they know that winning against Bayern Munich is quite difficult. The first meeting against Bayern Munich only ended in a draw and it is possible that in this second meeting the result will still be the same. But it is quite worrying if Bayern Munich wins and at that time Leverkusen will start to be overtaken.
Even being on top of the league, Bayern Leverkusen will be feeling all the pressure because it's better to chase someone at the top of the table than being chase because only the pressure and demand to be consistent can make you flop so I think Bayern Leverkusen will have to be at their very best if they do want to actually salvage this season bundesLiga title and believe me it would be nice to see Another team win this other than the normal winners of the league and I just hope Leverkusen doesn't fall to the pressure like the Dortmund did at the last minute of the season last year.
Borussia Dortmund was very unlucky last year and lost the championship in the last minute of the last match. I don't think we will see a similar scenario for Leverkusen this year. I don't see any team that can beat Leverkusen this year, other than Bayern. The match they will play against Bayern Munich this week will be a very critical match. It will be enjoyable for two teams with championship claims to compete against each other.
