Andy Murray believes he can become the first British winner of the French Open since Fred Perry in 1935 as he prepares to face Stan Wawrinka in the last four.
Murray, 29, plays the defending champion from Switzerland on Philippe Chatrier after 14:00 BST on Friday.
World number one Novak Djokovic plays Dominic Thiem in the other semi-final.
In the women's draw, Serena Williams takes on Kiki Bertens and Garbine Muguruza plays Sam Stosur, with both matches getting under way at 12:00.
British number one Murray has been to the last four at Roland Garros on three previous occasions, losing to Rafael Nadal in 2011 and 2014 and Djokovic in five sets last year.
Murray has won eight out of 15 previous meetings with 31-year-old Wawrinka, but has lost their last three - and all three on clay.
However, Murray has improved significantly on the surface in the past two years and beat Djokovic in the Italian Open final before heading to Paris.
Third seed Wawrinka, who won the tournament last year and the Australian Open in 2014, still feels his career is inferior to Murray's despite matching the Scot's tally of two Grand Slam titles.
