If Kane is really brought in by Madrid, maybe this will add to Madrid's attack line even stronger, especially since Benzema is not playing for Madrid so with the addition of attacking players to have even better quality attack lines.
I think for next season, Madrid really needs a change of players in the attack line so that in every game they can provide more scoring opportunities.
For Victor Osimhen, it might be easy for Madrid to take him, but for Mbappe, I'm not sure that Madrid can get this great young player because of course PSG will keep him so he can play for PSG a little longer.
I am not really sure if Harry Kane is really a candidate for Real Madrid. So far i think this are all just rumors. I mean it totally makes sense that Real Madrid is also thinking about Harry Kane because now that Karim Benzema has left the club they need a new number 9 and they also need it pretty fast. Looking at the market there are only a few players that may have the same level as Benzema and Harry Kane is definitely one of those. He is already 29 years old though and it looks like Tottenham wants a lot of money for him. As a club i would rather spend 100 M€ on a player that is 25 years old than on a player that will be 30 in a few weeks.
