No definitive decision has yet been made regarding Harry Kane. But I heard that Man United might not sign him. Tottenham are not willing if he still plays in one competition. So the big hope, maybe he will go to Manchester United or to Bayern Munich. Not only Kane, Bayern Munich is also in the search for a replacement for Lewandowski because Sadio Mane did not perform as desired. Bayern even approached Randal Kolo Muani of Eintracht Frankfurt and Rasmus Hojlund of Atalanta.
After Lewandowski left, they couldn't replace him, but they still managed to become champions. Mane was far below the expected performance. I don't think he's that good of a player anyway. If Bayern transfers a strong striker like Kane, they will become champions much more easily.
In addition, Lothar Matthäus says 5-6 players will leave Bayern. This means that they will have to transfer more players as well. I don't think they need to spend a lot of money though.
