I don't think Manchester United will go towards such high transfer fees. Manchester United will probably give a figure of around 80-100 million Euros, which Bayern Munich has already given, but Tottenham is not willing to sell. Harry Kane is a great football player and he wants to be a champion. That's why the Bundesliga may appeal to him more.
MU doesn't even have money to buy hojlund which worth around 80 millions and how can manchester united buy kane from totenham? It's an impossible thing to happen. Totenham is still waiting for the decision from kane. Kane already reached personal agreement with bayern but he was much more interesting in moving to the manchester united instead of bayern. Bayern is still finalizing the deal with spurs about kane's fees. Bayern can't afford to pay 100 millions for him.
The club wants Spurs to lower their price for Kane to under 10 million, but it's unlikely since Spurs want to make a lot of money by selling Kane..
The situation is still remain unclear at this moment. I hope kane will try to decide it as soon as possible. The kane's price has been preventing manchester united to make its first bid for him.
