Britain's former Davis Cup physio says Andy Murray will overcome the physical problems that have dogged his career.
Murray is still growing physically
Murray has climbed into the world's top 70 this season but has struggled with injury throughout his meteoric rise.
But Mark Bender said: "He's a teenager who has had a massive increase in the physical demands on him. These niggles are just a stage for him.
"Give him 18 months and he will be a pretty impressive athlete. He could end up like Marat Safin."
Murray beat Tim Henman in three sets on Wednesday at the Swiss Indoors to underline his potential.
But he was forced to quit the Ethias Trophy earlier this month with hamstring injuries and struggled badly with cramp during his defeats at Wimbledon and the US Open.
Bender is convinced the 18-year-old will out-grow the difficulties.
"There isn't anything wrong with him," he told BBC Sport. "He is a work in progress and will continue to improve.
"The huge thing for Andy too is the emotional intensity he brings to the game.
"What I see when I watch him in the last few months is that he's more relaxed and less tense, and that allows his body to react in a more appropriate way.
"As he calms down a bit and doesn't feel the pressure of being out there against a top-10 player, as he relaxes into his sport at the highest level, so the mental intensity will diminish and he will be able to play his game.
"It won't all become too much for him, as it was on occasion in the summer.
"I think he's being well looked after. A lot of thought has been put into his schedule, he's got a brilliant coach in Mark Petchey and he's got good conditioning people looking after him."
Murray plays his second-round match in Basel on Thursday.
