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.
I believe Tottenham will not sell Harry Kane this summer because they do not want him to leave the club now, which is why his transfer fees are quite high. His performance last season was very fantastic, as he was the second top goal scorer in the Premier League, and I believe he will perform even better next season. But I would like Harry Kane to leave Tottenham before the season begins; if he wants to win trophies, he should leave the Premier League and join another European league such as La Liga or League 1. I would also like him to join Real Madrid so that he can do great work and win the league with them, but I see Real Madrid are not interested in signing him again; they are focusing on other mbappe. Harry Kane need to leave Tottenham so that he can win champion league and other achievement, if he join another top team in Europe.
