I don't think they might be able to go ahead of Bayern Munich but that doesn't mean I have written them off from the race to be frank also.
They are quite scary to be frank and I know Munich would be mindful of them because any mistake that would take Bayern Leverkusen ahead of them would likely mean they lost the league again them twice in a role. I just hope Harry Kane can lift a trophy this season and Bundesliga title would be one of the best for him to lift aside the Champions League which is more unlikely this season.
Kompany will certainly be doing his best to make sure the Bundesliga title is theirs this season and the hard work will be done to secure that position. A seven-point lead over Leverkusen is enough for Bayern Munich to secure the title but they can't afford to make any mistakes in the remaining games. Harry Kane is quite enthusiastic about this because he has long failed to give his best for the club even when he was at Tottenham.
The Champions League is much tougher and there will probably be a lot of competition from other teams that are much stronger so the Bundesliga is a much more reasonable target this season that Bayern Munich can get.
