Novak Djokovic and Rafael Nadal will play a charity exhibition match at the Bernabeu Stadium on July 14.
The event is to raise money for the Real Madrid Foundation and the Rafa Nadal Foundation, which both use sport as a tool to encourage social integration.
It is hoped the chance to see the top two tennis players in the world in action will attract a crowd in excess of 80,000 people.
Nadal is a passionate Real Madrid fan.
