Cape Town - Former world No 8 Janko Tipsarevic has backed Andy Murray to "come back stronger than ever" and add at least one more Grand Slam trophy to his cabinet.
Three-time major winner Murray is currently undergoing rehab following hip resurfacing surgery in January, but he has previously admitted that he is not certain if he will be able to return to competitive tennis.
He also acknowledged that even if he does make a comeback, he is unsure if he will be able to compete at the high levels that he used to.
During a wide-ranging interview with that covered his own struggles with injury, his mental health as well as Novak Djokovic's comeback, Tipsarevic gave Murray his backing.
"Andy Murray will be back stronger than ever," he said. "This is the first place where your listeners can hear it. He will win another Slam.
"I'm not sure if he will be back to world No 1, but he will be back stronger than ever. I'm 100 percent sure of it."
When asked by host David Law how he can be so sure, he replied: "I am sure. Same like when I was speaking to Novak after his elbow surgery. For Novak it was a little bit easier because I was around him.
"I am not a huge religious guy, but I believe that the universe recognises if you really want something. Andy Murray, in my opinion, is completely obsessed about tennis, which is an unbelievable gift and a great thing. If he wants something really badly, there is no way it will not happen."
