In the end, they still need a great scorer, not just a striker, but someone who looks to score at all times, Kane could be the best option available right now, but if they can't, they shouldn't lose too much time trying to get him and try to find someone else that could work for them in the end.
but it seems that Tuchel is really serious about signing Kane. Tottenham also did not want to lose him actually. as there are rumors Tottenham is again offering a better salary to Kane. but it's possible that it wasn't what Kane was expecting. he could have moved to Munich as long as Munich had enough money to make up for it.
Tuchel looks like he will completely overhaul his team for this season. several players are reportedly ready to be released including Mane. and maybe this is also one of Munich's efforts to bring in Kane.
