The Top 2 tennis players of the World, Novak Djokovic and Rafael Nadal will square off in a charity tennis match at Real Madrid’s Bernabeu Stadium in Spain on 14 July, aiming to attract 80,000 fans to this event.

Nadal, a long-time fan Real Madrid, is working to help the club raise charity, the Real Madrid Foundation, to raise money for the Rafa Nadal Foundation. The proceeds generated will support causes coordinated by both the organizations.

Should the event hit its target turnout, it will smash the Guinness World Record for attendance at a tennis match of 35,681 people, set by Kim Clijsters and Serena Williams in July 2010.

Djokovic and Nadal have produced one of the most exciting rivalries on the ATP World Tour, with Djokovic winning seven straight meetings, all finals, to pull within two matches of leveling their head-to-head count which is lead by Nadal 16-14.
