Rafael Nadal and Novak Djokovic agreed their French Open quarter-final started too late after their four-hour match ended at 01:15 in Paris - 00:15 BST.
Asked if is was too late to be playing, Nadal said: "It is without a doubt. I understand television pays a lot of money but we need to find a balance."
Djokovic added: "Broadcasters say it's going to be night match, day match. They give the money. They decide."
Spanish fifth seed Nadal, going for a record-extending 14th men's singles title at Roland Garros, won 6-2 4-6 6-2 7-6 (7-4) against Serbia's Djokovic.
