Djokovic reaches quarter-finals in ominous fashion
Djokovic, also in the last-chance saloon as far as his Olympic title hopes go, beat Germany's Dominic Koepfer 7-5 6-3 to reach the last eight at the Games for a record fourth time where he meets Greek Stefanos Tsitsipas.
Serbia's Novak Djokovic and Spain's Carlos Alcaraz stayed on collision course for a golden showdown at the Paris Olympics as they surged through to the quarter-finals on Wednesday.
But Rafa Nadal's hopes of writing one last golden chapter in his Roland Garros love story ended in disappointment as he and Alcaraz lost in the quarter-finals of the doubles.
"I don't know what's going to happen in the future, but if that's the last time I enjoyed it," the 38-year-old said after a 6-2 6-4 loss to Americans Rajeev Ram and Austin Krajicek on the court where the king of clay won 14 French Open titles.

Tokyo Olympics singles champion Alexander Zverev stayed on course for a repeat as the third seed beat Australia's Alexei Popyrin 7-5 6-3 to set up a quarter-final with Lorenzo Musetti.
Women's singles top seed Iga Swiatek became the first player from Poland to reach an Olympic semi-final as Danielle Collins retired trailing 4-1 in the third set of their scrap.
Anna Karolina Schmiedlova stunned Wimbledon champion Barbora Krejcikova of the Czech Republic 6-4 6-2 to become the first Slovak since Miloslav Mecir in 1988 to reach the Olympic singles semi-finals and China's Zheng Qinwen ended the stellar career of Germany's Angelique Kerber to emulate Li Na who reached the semi-finals of singles at the Beijing Games in 2008.
Kerber, who will retire after the Games, clung on grimly in stifling heat but Zheng eventually won 6-7(4) 6-4 7-6(6) to set up a semi-final with Swiatek.
Swiatek trounced Collins 6-1 in the first set, lost the second 6-2 and was hit painfully by a Collins shot in the decider before moving 4-1 ahead, at which point Collins pulled out.
