Tottenham Hotspur have reminded Real Madrid regarding a 'friendly clause' in Gareth Bale's deal from back in 2013, according to Spanish publication MARCA (via Managing Madrid).Real Madrid signed Gareth Bale from Tottenham in the summer of 2013 for a then-world-record fee of £86 million. However, as part of the deal, Spurs included a friendly clause. That means Real Madrid were due to play a friendly match with Tottenham, a game that has not yet taken place.Despite Bale rejoining Tottenham on loan last summer, the friendly clause is yet to be activated by Real Madrid, even after eight years since the deal between the two clubs took place.However, there seems to be no time frame for the friendly to take place. Due to the ongoing global pandemic, Real Madrid are set to have a quiet pre-season with no trips to USA or Asia.According to the Sports Bible, Tottenham have requested Real Madrid for this friendly to take place this year, as such friendlies are a huge source of income for the involved clubs.Also Read: Fabrizio Romano's Transfer Roundup: Updates on Cristiano Ronaldo and Lionel Messi's futures, Arsenal active in the transfer market, and more.Tottenham are set to play Real Madrid in a pre-season friendly as part of an agreement from the Gareth Bale signing.https://t.co/WlrOmd7gKW— SPORTbible (@sportbible) July 5, 2021Gareth Bale looks set to feature for Real Madrid this seasonGareth Bale had a torrid time in Madrid under Zinedine Zidane.
