For the new season, whether you believe it or not is related to the performance of these two clubs because for me Bayern Munich can return to their previous performance to dominate the Bundesliga because Leverkusen also has to divide their time between appearing in the Bundesliga and Champions League.
Meanwhile, dividing the schedule in different competitions is something that is difficult and Leverkusen has no previous experience.
The issue with Harry Kane is that he needs to score more goals in the important games. Now at the European Championship there wasn't much coming from Kane. Penalties and one goal, the header against Slovakia which was decent positioning but rather expected from him to score that easy goal.
But Bayern doesn't gain anything from Kane scoring 40 goals in the Bundesliga when eventually they lose the important matches because Kane gets neutralized in a smart way by the opponents.
He is a good striker, but Bayern has some problems on the wings at the moment. Sané is way too inconsistent, Coman is injured frequently, etc. I think Leverkusen will play another strong season although I don't think Bayern will be as weak as last season.
