An 18-year rivalry will play out its next gripping chapter at Roland Garros as Andy Murray and Novak Djokovic eye up a French Open final in which milestones galore will be on the line.
Will Murray become the first British man to lift the French Open trophy in more than eight decades?
Or will Djokovic have enough energy left in the tank after playing four days in succession at the rain-ravaged claycourt grand slam to become the first man since Rod Laver almost 50 years to hold all four majors at once?
What is certain though, is that the Musketeers' Cup will have a new name engraved on it come Sunday - weather permitting - after Djokovic pulled rank on a player he described as "a leader of a new generation" to reach his fourth Paris final in five years.
Djokovic is 0-3 in title matches at the French Open, losing to Rafael Nadal in 2012 and 2014, then Wawrinka in 2015, each time in four sets.
Back in 2012, Djokovic also was on a 27-match winning streak at Grand Slam tournaments, just as he is entering Sunday.
