Marian Vajda, Novak Djokovic's coach, tells ESPN.com that it’s not only his pupil who's become gluten-free, but that his wife and two daughters have as well. "They started just for health wise. I am doing it when I'm with my wife, but when I'm not with her, I take a beer or a little sausage," he said with a laugh."
Vajda also said that some of the keys to Djokovic’s success are improved strength and fitness, his ability to stay positive when he doesn’t play well, as well as a harder forehand. "When we started to prepare for the Australian Open, I told him he has to have a faster forehand,” he said. "I gave him an exercise to make it faster, and during practice sessions and matches, he sped it up a bit more. It's not only the hands but the legs. He's very agile and flexible and so he can reach everything, but he has to use his legs."
He also discussed Djokovic’s failed experiment with having two coaches, Vajda and American Todd Martin, which ended in the spring of 2010. "There was bad communication," Vajda said. "It was really counterproductive. He went down with the serve; he couldn't serve last year. It was terrible. Everything was tough. Novak never had the impression to [avoid] work, but the communication was different. Todd was a big player and also wanted to try something new. But Novak was all set up, he only [needed] small improvements."
