A number of former Grand Slam champions have entered the coaching ranks recently. Stefan Edberg is coaching Roger Federer, Boris Becker is working with Novak Djokovic, Michael Chang is coaching Kei Nishikori and Sergi Bruguera joined forces with Richard Gasquet. Ivan Lendl has coached Andy Murray to two Grand Slam titles and the Olympic gold medal.
"I always say the best coaches are ex-tennis players,'' Ivanisevic told the Sun Sentinel. “If they want to coach and if they have time now everybody's coming back. … We should have a coach's tour."
Cilic, who worked with coach Bob Brett before starting up with Ivanisevic, said the former Wimbledon winner has already helped improve his serve.
"Goran showed his passion that he wanted to help me,'' said Cilic. "Already, he's helped my serve and to become more aggressive. It's a huge difference when you come to the Grand Slams and they know how to deal with what to work on, how they practiced. Goran is a great character, who loves and knows tennis. All that's a perfect combination.''
