Federer, 35, is also the second oldest man to make the quarter-finals at Wimbledon behind Ken Rosewall who was 39 when he reached the last-eight in 1971.
"It's their turf", said Ernests Gulbis, who stood in Djokovic's way in the third round but failed to present too much of an obstacle. In addition, that so-called Big 4 accounts for eight runner-up finishes during that stretch. She has dropped sets along the way but her game is constantly improving. I think until this year he hasn't played so well on the grass himself.
"I wouldn't say it's favouritism". "So I'm not that surprised".
Did Lendl think this would be the most challenging second week at a Grand Slam tournament that he had faced with Murray?
Federer is in the fourth round for the 15th time. Indeed, this is just the second time in his career that he has reached the second week of a Grand Slam.
Speaking of the Mladenovic-Riske matchup, both players also noticed how some sections of their allotted Wimbledon court seemed to be less like turf and more like slippery ice.
At the same time, newly-crowned French Open champion Jelena Ostapenko of Latvia faces Ukrainian fourth seed Elena Svitolina, one of the form players of 2016, on court 12.
As Federer alluded to, it's been Djokovic and Murray who arrived at the All England Club having been less than their best this season. Murray struggled in the opening set trailing Benoit's balls when the Frenchman showed erratic groundstrokes giving away points that settled in a tiebreaker. Monday's match against Paire, Murray said, was his best so far in the tournament.
Of the 16 survivors in the men's draw, Muller is most likely to be seen following his serve into the net - a tactic he has employed on a quarter of his deliveries so far, racking up an impressive 82 percent success rate. No. 18 Roberto Bautista Agut, and No. 24 Sam Querrey vs. Kevin Anderson.
Berdych awaits the victor of the Djokovic-Mannarino clash.
The victor will advance to the quarter-finals and face either Sam Querrey or Kevin Anderson. No. 10 Alexander Zverev; and 2010 runner-up Tomas Berdych vs.
Most parts of England experienced a heat wave a week-and-a-half prior to Wimbledon, with several days of warmer than usual temperatures following last week.
Old stagers Agnieszka Radwanska, the 2012 runner-up, tackles former French and US Open champion Svetlana Kuznetsova.
The ladies event, in stark contrast, still has a much more open feel and if Venus Williams can not become champion for a sixth time - and she would have to be by some distance the oldest in modern times at 37 to do so - then it's extremely hard to identify an obvious first-time victor.
Halep, who will become the new world number one if she makes the semi-finals, next faces Britain's sixth seed Konta. No. 21 Caroline Garcia.
"So it's great if you have someone like Jo or Kyle Edmund or whoever it is, just different players to follow".
"I came through the juniors with all these guys".
"The top guys are top guys because they do things a little bit better than the other guys", Ivan Lendl, Murray's coach, said here on Sunday after guiding his charge through a practice session at Aorangi Park. "But then there's a strong, strong team, as well, around the generation of Rafa and Murray and Djokovic, obviously".
