Three-time champion Novak Djokovic, seeded a lowly 12 this year, can make his 10th Wimbledon quarterfinal if he defeats unseeded Karen Khachanov, the world No. 40 from Russian Federation. That year Federer beat Gilles Simon on No. 1 Court in the quarterfinals.
"I think psychologically there's a huge difference for Anderson to play on Court One rather then Centre", the Swede, working as Eurosport's chief analyst, told Reuters.
Del Potro trails world number one Nadal 10-5 in career meetings.
"It's what I wished for", said Djokovic when asked if he would have preferred to move to Centre Court.
Since seeds were introduced in the 1920s, it's the first time none of the top-10 have reached the women's quarterfinals at Wimbledon.
Monday's win took Nadal, 32, into a 35th Grand Slam quarterfinal.

Williams is looking for her eighth Wimbledon title and has established herself as the big favorite once again.
"He's a big-match player", Djokovic said of the former US Open runner-up.
Hsieh's protests to the umpire prompted the match referee to come on court to intervene as the argument lasted over seven minutes before the point was finally replayed, much to Cibulkova's disgust.
The seventh-seeded player was defeated by Kiki Bertens 6-3 7-6.
Beaten by Serena in the 2016 final, Kerber takes on Russian 14th seed Daria Kasatkina, a 6-7 (6/8), 6-3, 6-2 victor against Belgian world number 47 Alison Van Uytvanck. It shouldn't be a shock, and, "Oh, my God, I can't believe it, I lost a set".
Despite being a three-time champion, Djokovic has featured just once on Centre Court - against British home favourite Kyle Edmund in the last 32 - in the opening four rounds. "I will try to hold my service games most of the time. It will stay this year, it will stay next year", said All England Club chief executive Richard Lewis.
She served for the victory at 5-4, but got broken.
He has sent down 96 aces in four rounds and dropped serve just six times.
Del Potro is in his first quarter-final at the tournament since 2013 when he reached the semi-final.
Yet Federer quickly snuffed out the danger and broke in the next game before rounding off the match in typically ruthless fashion.
The 2009 U.S. Open champion reached the semifinals at the All England Club in 2013, but four wrist surgeries - three on the left - nearly made him retire.
World No. 1 Rafael Nadal is realistic about who he wants to face should he reach the Wimbledon final this year. "In 2017 I played well, 2018 I am playing well".
The only remaining fourth-round match has also resumed on No. 2 Court.
The last-16 tie between Del Potro and Frenchman Simon was suspended overnight due to darkness on Monday with the Argentine fifth seed two sets to one ahead.
The road to recovery following elbow surgery has been rocky for Djokovic, but there were signs of a revival during the clay-court season, which included a run to the French Open quarter-finals, while this rebirth was all-but confirmed with his display at Queen's last month.
If he ever decides to stop playing tennis, Roger Federer may have a future in another sport.
Ten years ago, the 2008 Wimbledon final between Rafael Nadal and Roger Federer was played.
Whether it was a forward defensive shot or a back-foot cut, the eight-time champion's technique impressed the International Cricket Council.

The 28-year-old Nishikori is the first Japanese man to reach the quarterfinals at Wimbledon since Shuzo Matsuoka in 1995. The world number 40 was unable to mount a response this time and evidence fortune was in the Serbian's favour came on his second of two set points when a Khachanov slip enabled him to take a 2-0 lead in the match.
