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.
I think Bayern will be ok and they don't have to worry about anything. Historically, Bayern always comes out on top because even if they mess and up leave points on the table other teams that could cut into Bayern's lead never take advantage of this big possibility. I don't know why this happens so often, same with Bayern more than often winning games in the last minutes. In German that the so called "Bayern Dusel", which translates to some sort of luck.
