 Novak Djokovic is looking forward to playing at Wimbledon. He says that his right knee has responded well after surgery to repair a torn meniscus that was suffered less than a month ago when he was playing the French Open. And the grass court at Wimbledon has already been friendly to Djokovic, where he's won seven of his 24 Grand Slam trophies. He said that earlier he doubted whether he would make it after getting injured yesterday.
