Bayern Munich is doing very well this season but it is also because they have not had to face many strong teams. They have won some games just by luck but overall they have played very well and are now far ahead in league.
Bayern Munich has performed very well this season and the victories they have achieved are entirely because they have indeed performed stronger than last season so it is not because of luck, while Leverkusen who has been Bayern Munich's main competitor in the last two seasons has not played as well as last season even getting a lot of draws and has experienced 1 defeat. Bayern Munich has also experienced 1 defeat and only experienced a few draws therefore the difference in points between them is quite far, for now Bayern Munich can sit comfortably at the top of the standings without worrying about Leverkusen being able to take their position.
