Considering Bayern Munich is already way way ahead of everyone else, and Bayer Leverkusen couldn't even get a win, this loss doesn't mean anything to Bayern. Even if Leverkusen got a win, Leverkusen would have been 56 points after the win, whereas Bayern is 61 points, that would still be a six point gap.
But right now, that is not even the case, the results are both losses, meaning Leverkusen is at 53 points, and Bayern Munich is at 61, making the gap 8 points right now, that is a quite important result. Kane will finally get a trophy, it is a horrible feeling to be this great and still have no trophy at all, I am sad for him, but there is nothing that can stop Kane from getting his first silverware this season.
