Has been the runner-up at Roland Garros on three occasions. Needs another $300,000 to become first player to win $100,000,000 in prize money. ANDY MURRAY (GBR) World ranking: 2 Age: 29 (15/05/1987) Career titles in total: 36 Career Grand Slam titles: 2 -- Wimbledon: 2013; US Open: 2012 - Murray is a three-time semi-finalist in Paris and goes into this year's tournament having defeated Djokovic on clay in the Rome final last week. Steadily progressing on clay after only winning his first titles on the surface in 2015. ROGER FEDERER (SUI) World ranking: 3 Age: 34 (08/08/1981) Career titles in total: 88 Career Grand Slam titles: 17 -- Australian Open: 2004, 2006, 2007, 2010; French Open: 2009; Wimbledon: 2003, 2004, 2005, 2006, 2007, 2009, 2012; US Open: 2004, 2005, 2006, 2007, 2008 - The 2009 French Open champion would normally be considered amongst the title favourites but the Swiss legend has played just four tournaments all year after battling knee and back injuries. RAFAEL NADAL (ESP) World ranking: 5 Age: 29 (03/06/86) Career titles in total: 69 Career Grand Slam titles: 14 -- Australian Open: 2009; French Open: 2005, 2006, 2007, 2008, 2010, 2011, 2012, 2013, 2014; Wimbledon: 2008, 2010; US Open: 2010, 2013 - Nadal has a record of 70 wins and just two defeats at Roland Garros since his 2005 debut. Written off as a spent force 12 months ago when he exited in the quarter-finals, the Spaniard has clay-court titles this season at Monte Carlo and Barcelona. STAN WAWRINKA (SUI) World ranking: 4 Age 31 (28/03/1985) Career titles in total: 13 Career Grand Slam titles: 2 -- Australian Open: 2014; French Open: 2015 - The performance of a lifetime gave him a shock title in 2015 and left Djokovic in tears. The Wawrinka single-handed backhand which was so instrumental in his win 12 months ago has been under-powered in 2016 with a quarter-final run in Monte Carlo his best outing on clay. KEI NISHIKORI (JPN) World ranking: 6 Age: 26 (29/12/1989) Career titles in total: 11 Career Grand Slam titles: 0 - Runner-up to Nadal in Barcelona where he had been defending champion, Nishikori has traditionally endured a miserable spring in Paris. A quarter-final appearance last year is his best effort.
