World number one Novak Djokovic vowed not to play again on the controversial blue-clay court after a 7-6 (2), 6-3 defeat to Janko Tipsarevic in the quarterfinal at the Madrid Open.
After his defeat to Fernando Verdasco, Rafael Nadal said he wouldn`t return unless the tournament reverts to red clay on Thursday.
"I want to forget this week as soon as possible and move on to the real clay courts," Djokovic said. "Here you can`t predict the ball bounce or movement. They can do whatever they want, but I won`t be here next year if this clay stays."
It was Tipsarevic`s second win in five matches against Djokovic. He will now play either Roger Federer or fifth-seeded David Ferrer.
