Bayern Munich got problems with finding a good sticker and a player to finish balls for them that's the reason for Tuchel to ask the team to hire Kane. However, in the last time when they hire Sadio Mane, he had a perfect performance in Liverpool and scored many goals in that team but when he joined Bayern Munich he couldn't have a good performance that's why I think there is a chance to see the same story about Harry Kane.
Even though Harry Kane could perform better than Sadio Mane in Bayern Munich but it is absolutely possible to see the same story again. Just to remind about Lionel Messi poor first season with PSG. Even a top world class footballer could fail to adapt fast so they have to wait and give him a second chance if ever that happened.
Tuchel wants an excellent number 9 to drove the team to victories, this point is totally agreed by Bayern Munich staff, otherwise recruiting a number 6 isn't considered as a priority to them although Tuchel insisted also on that point.
I'm sure they'll have more patience with Harry Kane than with Mane. It was said that some football players didn't want Mane and I don't think that would happen for Harry. Harry is an important star as well as a compatible actor. We all know how good his relationships are at Tottenham. I hope he comes to Bayern and shows his performance in the Premier league soon.
