I disagree with what you mentioned regarding Leverkusen because the two teams are six points different, and Leverkusen still has the opportunity to close the gap with the games left in the season. I also assumed that Bayern had already won the Bundesliga title this season but since they drew their last match against Union Berlin, Leverkusen might win this trophy again this season.
Exactly, indeed initially Bayern Munich dominated the standing table in Bundesliga, because they were 10 points ahead, you are not wrong. However, lately, Bayern Munich's match results have not been so consistent. In fact, they only won 2x in the last 5 matches, which made the points difference with Leverkusen only around 6 points. This does not rule out the possibility that Leverkusen also has the chances to do it, although it's also difficult to be done, but not something impossible.Harry Kane has had a really impressive season so far. Maybe not better than last season but it is still a good effort. 41 G/A contribution in 37 games considering all tournaments this season. 
Indeeed, he is incredible, scoring many more goals, not only his role in Bayern Munich, in all matches, both Bundesliga, UCL, and other Leagues. So is his role and contribution in the nations League, for the England national team. even has scored 70 goals for England!
