Rafael Nadal and Novak Djokovic have met more than any other two men in the Open era - and the pair are ready to finally resume their long-standing rivalry on the Grand Slam stage.
Nadal, 32, and Djokovic, 31, meet in a highly anticipated Wimbledon semi-final at about 14:00 GMT today (Friday).
They have met 51 times, but not as deep into a Slam since the 2014 French Open, when they contested the final.
The winner will play either John Isner or Kevin Anderson in Sunday's final, the BBC reports.
Spain's Nadal and Serbia's Djokovic have won 29 Grand Slam titles between them, including five previous victories at Wimbledon centre court.
The pair have only met twice at Wimbledon, Nadal winning their 2007 semi-final when Djokovic retired hurt, the Serb gaining revenge in the 2011 final.
"There is no one other match in the history of tennis that has been played more than our match. That's a big thing," said second seed Nadal.
"We always played in important stages, important places."
