I'm not going to buy into this idea of throwing almost all the blame at harry cane, I means he's not the only player in the team, he's playing in his role which he's playing aswell and other players aswell should also needs to be playing well to compliment he's performance although I know he's the very important because of the role he's playing from the team but it still doesn't get to rest all on his shoulder just yet.

Collectively they all have a role to play in the success of the team moreover currently Kane appears to be injury prone and he's aswell aging and not a very young player who's got all the strength to deliver so much, after years of dominance, loosing can actually be really frustrating but then it's part of football as you can't be expect to always just get to win the league title because at some point its normal for another team to get to win at a point just like see in the Ligue 1 where PSG has always won the league title put lost it few seasons back to another team so it's definitely not much of a big deal.

Kane's recovery should be priority like you mentioned rightly so he will be able to deliver by next season optimally and ofcourse he's got time to be able to recover before the season resumes by next season, Leverkusen winning the league this season isn't all because there are other season for Munich to still get to recover and still get to win the league title as always but then after now I believe it's going to be a tough one unlike the regular one.
