Djokovic, Federer in Wimbledon landmarks as title showdown nears
The Serb tackles Marton Fucsovics, the first Hungarian man to get this far since 1948, looking to reach his 10th Wimbledon semi-final.
He faces 18th-ranked Hubert Hurkacz, only the fourth Polish man to make the last-eight after knocking out world number two Daniil Medvedev.
Having already become just the third man to win all four Slams more than once by lifting his second French Open last month, Djokovic now has another record in his sights.
He is halfway to a rare calendar Grand Slam, a feat only achieved by two other men -- Don Budge in 1938 and Rod Laver in 1962 and 1969.
As a result, the 34-year-old is already being hailed as the greatest player of all time, surpassing even Federer and the absent Rafael Nadal.
"I feel privileged and honoured of course and very happy to be in this position to make history in the sport," said Djokovic who can win his 100th grass court match on Wednesday.
Left in the tank
Djokovic enjoys a 2-0 head-to-head record over 29-year-old Fucsovics who has made the last-eight of a Slam for the first time.
Fucsovics knocked out fifth seed Andrey Rublev in the fourth round in five sets after the Russian had swept their previous four matches in a nine-month spell.
"I think I will become famous now in Hungary," he said.
"It's a big thing. But for the moment I'm not thinking about what will happen in Hungary, if I will be in the news or if people will talk about me."
Worryingly for the Hungarian, Djokovic has only faced nine break points through four rounds at the tournament.
He struggled in his opener against Adrian Mannarino who had to retire injured at two sets each.
"I felt like now I've had some good progress. I'm taking the ball earlier. Obviously I've gotten used to the conditions, gotten used to the balls, the court speed," said Federer whose comfortable last-16 win against Lorenzo Sonego was the 105th of his Wimbledon career.
Should Federer reach the semi-finals for the 14th time, he will face either Italian seventh seed Matteo Berrettini or Felix Auger-Aliassime, the 16th-seeded Canadian.
He has fired a tournament-leading 67 aces and dropped serve just twice.
Berrettini reached the quarter-finals at the French Open last month where he lost to Djokovic.
Auger-Aliassime, 20, is in the last-eight of a Slam for the first time after knocking out German fourth seed Alexander Zverev in five sets.
The two are close friends while their respective girlfriends are cousins.
Auger-Aliassime is dating Nina Ghaibi while Berrettini is romantically involved with Australian player Ajla Tomljanovic who lost in the women's quarter-finals on Tuesday.
Berrettini defeated his friend in the final of the Stuttgart grass court final in 2019.
Wednesday will see two Canadian men in the last-eight of a Slam for the first time with Denis Shapovalov taking on Russia's Karen Khachanov.
Shapovalov, a quarter-finalist at the US Open last year, holds a 1-0 career edge over Khachanov, who made the French Open last-eight in 2019, following a win at the 2019 Davis Cup.
Left-handed Shapovalov followed up his win over two-time champion Andy Murray with a straight-sets victory over 2019 semi-finalist Roberto Bautista Agut.
