I don't think Real Madrid will complete Harry Kane's transfer if Tottenham set such a high price for him. I think Real Madrid would likely complete Mbappe tranfer for the same value if they were willing to spend that amount on a striker. But instead of buying an expensive striker, Real Madrid have an alternative where the unexpected Joselu has become Real Madrid's latest signing as a striker.
Jesulu may only have a short-term contract with Real Madrid as he was the only alternative being considered after Real Madrid lost Benzema. If Real Madrid don't find their best new striker, then they might do it again in another transfer market while following developments on Mbappe's situation at PSG.
Harry Kane chapter for the Real Madrid is already ended because Real Madrid is not going to invest amount which is tagged by Tottenham for the transfer of this star player now they are working on few alternative players with Mbappé is still their main target, but they will also not pay price which is currently tagged for him as well which is surely too much for them even they can afford this and situation at PSG is also not good because if he is not going to extend his contract then most chances PSG will off load him, and we have few clubs which can invest this amount like Chelsea, Newcastle United and Manchester United so now where he is going it's not clear because if he will join any English club then surely Real Madrid is going to lose this chance for the next four or five years.
Real Madrid already have some good signings even these are not as par requirement but still they are working on their target and who is coming to be their next signing for the main spot it's not clear, but all will be settled in next few weeks
