To be fair that did not ended up being all that important. I am not saying that Kane did not help, but even with all that scoring, they still lost the league for the first time in over a decade and that means something. Is it because of Kane?
Of course not, he did not made them lose, he even helped them win so many games with his extra scoring ability, they lacked that last season and they really needed a striker and I still think that they overpaid for him but he did showed the world that he means business and did alright. And yet, they won the league last year (barely) and lost it this year. So, we need to realize that there is something else that went bad and as long as Bayern doesn't find that, they are not going to benefit.
It's obvious that they blame Tuchel for this since they decided to replace him. But what’s surprising is that they agreed to keep him in the team and even negotiated with him about it, but they couldn’t come to an agreement because Tuchel demanded a longer contract, but they signed a contract with Kompany for three years, which also looks too confident on their part , for such a young coach without much experience. This decision seems hasty to me for now, but we’ll see how it ends in a season.
