Andy Murray will be looking for weaknesses to exploit at the French Open when he takes on Rafael Nadal in Rome tonight.
The long-time friends have not played each other for three years, during which time both players have battled injury and Murray has become a two-time grand slam winner.
Tonight's Rome Masters quarter-final represents an opportunity for Murray to improve his poor record against clay-court tennis' undisputed king: the Scot has taken just one set in four meetings on the surface.
But Murray is already thinking ahead to Roland Garros, where Nadal will be aiming for a ninth French Open title later this month.
"It's a good test with the French Open just around the corner," he told Sky Sports.
"Potentially I could play him at the French, so to get a test and a feel for his ball and see which things work against him on the court will be very beneficial."
Murray has won five of 18 career meetings with Nadal, who has reached the last eight for a fifth straight tournament.
"If he loses in semi-final or before it's a huge shock," Murray said.
"The whole time I was with (former coach) Ivan Lendl we never played - it's been a good three years since we played each other, which is strange.
"I've always enjoyed playing against him - it's a good challenge. His results on clay have been incredible over the years."
