Harry Kane will be able to win a title this season and it will be a great achievement for him, we can say for sure that they will be champions of the Bundesliga this season. Last season Leverkusen was in great form and they were champions but this season they also lost in the Champions League and are not favourites to win the Bundesliga title. Bayern Munich's morale will definitely be boosted as they have ensured that they will win the Bundesliga this season, besides they have a good chance of winning the Champions League title as well.
This is the momentum that Harry Kane has been waiting for with Bayern Munich because the Bundesliga title race is getting closer for them to get this season. But for the Champions League I think the chances that Bayern Munich have are very small because they have to go through difficult matches to reach the final and we know the competition in the Champions League is much tougher.
Winning the Bundesliga title will indeed give Bayern Munich a little higher morale but if they are unable to face the pressure from the opponents they will face in the upcoming matches then it will be difficult for Bayern Munich to qualify for the Champions League final.
