ITV French Open pundit John Inverdale believes that past disappointments at Roland Garros may weigh heavily on world number four Andy Murray.
Having lost three Grand Slam finals time could be running out for Murray to end Britain's long wait for a major champion, and Inverdale admits those defeats will have affected the 25-year-old's self-belief.
"He's clearly not playing to the best of his game, only he will know if he's peaking at the right time," Inverdale exclusively told ITV.com.
"Whatever he says, assuming he plays Nadal in the semis, how, when you're leaving the dressing room before that game, do you tell yourself that you really, truly believe that you can win that match?
"How do you do that when you're facing the King of all Kings on clay?"
And Inverdale admitted that he doubts whether Murray can overcome those self-doubts.
"I'm not sure what answers he'll find for himself - other than if Nadal has a bad day," he said.
"So much of tennis is in the mind: do you genuinely believe you can win? And everyone says they do because if they didn't there'd be no point being there.
"But I wonder if that situation came to pass, would Andy Murray genuinely believe he could win?"
Even so, Inverdale said he was still motivated by the hope that he might witness a Murray victory at Roland Garros in 2012.
"I've been a tennis fan all my life," Inverdale said. "Wherever - if it's Roland Garros or elsewhere - I'd love to be there to see the first British Grand Slam winner in 70 years."
