The problem for the moment is the transfer of Kane and Madrid is actually still only centered on rumors and there is still no further development on this matter.
Tottenham seems like they will continue to keep Kane's price high enough because for now they seem to be preparing to lose him and of course a big profit should be made from this transfer even though this is not a big problem for Madrid but it seems that there is still no further movement on this matter .
What further development do you need? I'm sure Real Madrid management is trying their best to negotiate with Tottenham now. They surely won't tell the progress because there are many other teams interested to sign Harry Kane, too. Real Madrid will announce the progress when they already get the agreement from both Tottenham management and Harry Kane.
Of course, Tottenham will try to sell Harry Kane at the highest price because they probably use the money to buy a new striker as the replacement. But I think Real Madrid won't have a serious problem as long as the price deserves for the striker. Real Madrid won't pay the price if it is too expensive and nonsense.
Therefore they have to try further than this because indeed they have to realize that when they want something then they have to try more things.
Discussion about Kane is still floating up to now even though there is a lot of speculation now but of course we also know that this is now still in uncertainty.
If Kane is the best for them then it's not wrong for them to do the same as when they paid for Jude.
