Andy Murray and Novak Djokovic will meet in Sunday's French Open final - with both men seeking their first title in Paris.
Murray, the first British man to reach a Roland Garros final since 1937, hopes to add the French Open to his victories at the US Open and Wimbledon.
Djokovic, the world number one, can finally add the one major title to have so far eluded him.
It will be the pair's seventh meeting in a Grand Slam final.
Djokovic leads that head-to-head 4-2, their overall contests 23-10 and has 11 major titles to Murray's two - but it was the Serb whom Murray beat to claim his Grand Slam victories at the US Open in 2012 and Wimbledon in 2013.
The Scot also won their most recent meeting in the final of the clay-court Italian Open four weeks ago.
There is a huge amount at stake for both men in Sunday's final, with Murray again looking to match Fred Perry, Britain's last male champion in 1935.
Sue Barker won the women's title in 1976 but since then a surprise run to the semi-finals by Tim Henman in 2004, followed by three semi-finals for Murray, were the best any Briton had managed on the Paris clay.
It is the first final between two top seeds trying to win a Grand Slam title for the first time since Ivan Lendl beat John McEnroe in Paris 32 years ago.
Murray will hope to emulate the achievement of his former coach - and then second seed - Lendl, and he takes on a very familiar rival.
Both finalists turned 29 last month and have known each other since junior days - but Djokovic has taken a firm grip on their personal duel in recent years, winning 12 of their last 14 matches.
"We have had some really big battles in the Slams before on all the other surfaces," Murray said. "I'm sure it will be the same again on Sunday."
Murray needed five sets to beat Radek Stepanek and Mathias Bourgue in his first two matches, and four sets to beat Richard Gasquet in the quarter-finals, but played superbly to beat defending champion Stan Wawrinka on Friday.
Djokovic and Murray have stood at the top of the rankings for all but a week in 2016 - but the Serb has a huge lead and would hold all four Grand Slam titles with another victory over Murray.
Only American Don Budge in the 1930s and Australia's Rod Laver in the 1960s have achieved that feat, and just seven men have completed the career slam.
However, Djokovic has played three French Open finals without success, losing twice to Rafael Nadal and then suffering a surprise defeat by an inspired Wawrinka 12 months ago.
