Well considering Bayern are showing so much interest in him and reportedly already putting bids in, id say you're wrong. Bayern clearly want him now and not in 12 months and have backed that up by their constant courting him of him in every mdeia outlet they can for the past 12 months. If Bayern weren't that interested, they have a very strange way of showing it.Best solution for Bayern IMHO would be to loan in some winger for 15-20M for one season and then sign a contract with Leroy Sane on 1st January that starts 1st July 2021.
40m+wages is already an insanely high number to get a player some 10 months earlier, let alone 70m. You can get a loan deal much cheaper than that.
Further to that, between now and 1st January, Leroy Sane could prove that he's not the same player he was when he last played, over a year ago, and Bayern may decide that they wouldn't even need him on a free and end up signing the loanee instead.
I know you guys won't like this post, but tell me where I'm wrong if you think from Bayern's perspective.
