Bayern Leverkusen is below Bayern Munich with 6 points. There is no possibility that they can be able to win all the remaining games they have. Also, Bayern has more chances to get more point than Leverkusen from the games left to play.
Lots of possibility for Bayern to win the league so no need to elaborate much on this.
It might not possible for Bayer Leverkusen to win all remaining games neither is it possible for Bayern Munich to also win all remaining games too, so there are lots of impossibilities and also lots of uncertainties involved in the title race of the German bundlesliga this season and perhaps six points isn't a big deal and Bayern Munich needs to be extremely careful if they want to continue to be at the top of the table till the end of the season, they have to concentrate and never lose focus but maintain consistency because that is the only way for them to keep the Leverkusen side at bay if they intend to win the title.
