The world-class England forward would follow in the footsteps of Welsh winger Gareth Bale in making the switch from North London to the Spanish capital.
Having been with Tottenham's academy since 2004, Harry Kane's path to the first team was less than obvious, as he spent three seasons on loan at Leyton Orient, Millwall, Norwich City and Leicester City.
However, Tottenham will be very unwilling to sell their biggest and best player ahead of their move to a new stadium and Daniel Levy will likely look for something closer to the £198m that PSG paid to sign Neymar from Barcelona.
The discussion as to whether Kane is world class or not has started once again as he struck his sixth Premier League goal of the season on Saturday, taking his tally for club and country to 13 in September alone.
The Spurs star now has no plans to quit the club, and reports in Spain suggesting Real Madrid are preparing a mega-bid are understood to be premature.
Still so early into his career, the England global has the potential to reach incredible heights in the game and Real Madrid are willing to spend huge money to make sure he does so in La Liga. I think Cristiano Ronaldo's main goal in life now, Lionel Messi's maybe as well, is to win the Ballon d'Or as it shows they are the best in the world.
"They're totally different players - Harry's an out-and-out goalscorer and Gaz is a bit of a winger but in terms of development it's relatively similar".
He's been rewarded with the England captaincy for the Wembley game. It now remains to be seen if Kane becomes the latest Tottenham player after Bale and Luka Modric to make his way to the Spanish capital, or if Spurs manage to retain his services. While Spurs has improved dramatically under Mauricio Pochettino's guidance, becoming one of the most complete team's in English football, the Argentine is yet to win any silverware.
