Bayern already planned to get a new player from totenham. Bayern has even prepared an offer for harry kane from totenham. that being said that the current squad of bayern is not yet enough. Bayern needs to build the squad to be even stronger than before. I think that bayern has some names other than kane on its transfer list. Bayern is also trying to get a young talented player from its opponent dortmund. Bayern will be preparing its team to face the mid until end of season to make sure the team can win this season without any problem at all.
The fact that if these days there are many things happened with bayern. So many changes will come to the bayern during january
Not ready for what? They are already leading the league, and it is not easy to win UCL so they may lose that, who cares? As long as Bayern keeps on winning Bundesliga, and usually win their cup, and then go out of group stages of UCL and keep doing that every single year, without missing a beat, every year, then they will have financial freedom to keep the team at a good level to repeat that.
They already spent a good chunk of money to renovate the team, and I believe Kane would be just a useless money spent, and even if they do that, they won't need more players because that would be enough, their current roster is already enough if you ask me anyway.
