Former doubles star Luke Saville believes that Novak Djokovic must recall one of his former coaches if he is to bounce back to winning ways.

The Serb recently announced his split from working with ex-rival Andy Murray, and Saville believes that Djokovic needs to return to one of his most successful coaching partnerships as soon as possible.

Speaking on Tennis Channel, he said: "It's not easy to answer the question of whether Djokovic can still win a Grand Slam title, there are too many variables right now.

"After the end of his collaboration with Murray, I believe that Novak should seriously think about recalling Marian Vajda or Goran Ivanisevic. Both have had a very significant impact on his career and are perhaps the only ones who can help him.

"If the Serbian has another chance to win a Major, I doubt it will happen at Roland Garros. He definitely has a better chance at Wimbledon and the US Open."
