Organizers hope the event at the 80,000-seat stadium will break the world record for attendance at a tennis match, set last year when 35,681 fans watched Serena Williams play Kim Clijsters in Brussels.
Proceeds from the match will go toward the Real Madrid Foundation and the Rafael Nadal Foundation, both of which benefit disadvantaged children.
The match will take place in between Wimbledon and the Olympics, both of which will be held at the All England Club. Djokovic has won the last seven appearances with Nadal, including wins in the past three Grand Slam finals. He replaced Nadal as the No. 1 player in the world last July after winning Wimbledon.
The Clijsters-Williams match in Belgium broke the longstanding tennis attendance record, set at the Battle of the Sexes between Billie Jean King and Bobby Riggs in 1973.
