Novak Djokovic and Rafael Nadal could meet for the 50th time after they were placed on a French Open semi-final collision course on Friday.

World number one and top seed Djokovic, who turns 29 on the opening day of the tournament on Sunday, needs a Roland Garros title to complete a career Grand Slam after losing three finals in four years, including last season to Stan Wawrinka.

Should Djokovic and nine-time French Open champion Nadal meet in the last-four it will be their 50th career clash in a rivalry which began in 2006 at Roland Garros.

Djokovic has the edge at 26-23, claiming the pair’s last seven encounters.

Fourth seed Wawrinka is scheduled to take on second seed Andy Murray in the other semi-final.

Top seed Djokovic, bidding for a 12th career major, starts his campaign against Taiwan’s Lu Yen-Hsun, the world number 100 who made the Wimbledon quarter-finals in 2010.

Djokovic is seeded to face Tomas Berdych in the last-eight while he could tackle volatile Australian Bernard Tomic in the fourth round.

Tomic was accused by the Serb of lacking commitment after a tame exit at the Madrid Masters last month.

Nadal starts his French Open against big-serving Sam Groth of Australia with a potential quarter-final against home hope, and two-time semi-finalist, Jo-Wilfried Tsonga.

With his 30th birthday just around the corner, Nadal has arguably the toughest draw of the top men but will be buoyed by a recent return to form which saw him claim the Monte Carlo and Barcelona titles.

Murray will meet a qualifier in the first round with a potential quarter-final against Japan’s Kei Nishikori.
