Some of the women players "demoted" to the lesser courts were less than impressed about their treatment.
Federer is a seven-time champion at the All England Club and one of the fan favorites.
"It was frustrating last night, I must admit", he said. I try to make the most of it.
None of the opening five points went with the serve, but Djokovic recovered from 4-2 down to take it 7-5 and leave himself in complete control of the match.
Federer said he had learned to manage his body - citing last year's French Open when he arrived at Roland Garros struggling with knee and back injuries and chose to pull out of the tournament before it began.
Will Sam Querrey upset upset Andy Murray?
I like Djokovic to advance to the semifinals.
He added: '[They] need to maybe find a way of allowing for an equal split of the men's and women's matches across the tournament rather than just looking at one day.
Women's seventh seed Svetlana Kuznetsova found herself eliminated after a straight-sets loss to Garbine Muguruza, the 14th seed and 2015 victor at Wimbledon. A rejuvenated Federer returned at the start of 2017 to win the Australian Open, Indian Wells Masters and Miami Open, before marching to Wimbledon in terrific shape.
Federer first reached the Wimbledon quarterfinals in 2001 and then won the first of five straight titles in 2003. They were told fan safety was the reason why they did not move the match to Centre Court, which was vacant after Roger Federer's three-set victory over Grigor Dimitrov. I don't feel ready to go. "Still a huge match in front of me and in front of Roger, as well".
Next up in his litany of complaints was a hole on Centre Court, which he drew the attention of the umpire too. I think that's the difference. "I think our match was a very interesting one for the people to watch". "We were scheduled to play, as you know, after an epic match, Nadal and Muller".
"Marin is ranked, like, 5", the American said, mistakenly moving Cilic up a spot from his No. 6 ranking. Obviously not having the fifth-set tiebreaker here, it's kind of tough to predict when the match is going to end. And it was readily apparent in his match with Berdych that the lack of recuperation time on Tuesday took its toll, forcing Djokovic, who hadn't lost a set before Wednesday's opener, from the tournament. He's an established top-10 player, big game, flat shots, which are pretty good for this surface where the ball bounces quite low. "Potentially that can hurt anyone in the game".
