Federer beat Raonic in the 2014 semifinals, then lost to him in last year's semifinals.
Yet Djokovic then found his best form and went on to take the set 7-6 and assume total control on the last-16 match. The grass-court season was hard because of the back issues I had, and the knee issues.
Tournament officials have defended their decision to put four men's matches and only two women's on Wimbledon biggest courts on Monday, saying that star player appeal over-rides any idea of equal allocation by gender.
Novak Djokovic admits his battered body needs rest after a chronic elbow injury cruelled his hopes of a fourth Wimbledon crown.
Djokovic-Mannarino was to follow the Rafael Nadal-Gilles Muller epic, but when that match ran long, Wimbledon had the option as early as 7pm to move Djokovic to an empty Centre Court.
A double fault from Djokovic and some loose play allowed the Frenchman to break in the second set and eventually force a tie-break, but the 12-time Grand Slam champion came through the extra points easily. "It has something which has been dragging back and forth for a while, but I am still managing to play". I wanted to play. The Frenchman saved a set point when Djokovic missed a backhand down the line.
But Berdych seized the chance to add to Djokovic's woes with a break in the second game of the second set.
Arm pain slowed Djokovic's serve and seemed to diminish his explosive backhand.
Head to head: Cilic 4-0, including 3-0 on grass.
Sixty-three minutes into the match it looked like Mannarino might be content with a fourth-round result before riding off into the rain.
Djokovic said he and Mannarino were in communication with tournament organizers throughout the evening.
"It's the elbow that already keeps bothering for over a year and a half actually", Djokovic said. Hooking a forehand victor down the line, the 51st-ranked Frenchman wrapped a stylish service hold for 5-all.
After slipping in the rankings, Nole is aiming to get back on top.
It can hardly have made pleasant viewing for coaches Andre Agassi and Mario Ancic either, but if anything it focused Djokovic's mind. In between, Muller had to fight off a break point in the 13th game and 4 more in the 19th.
Berdych entered the match as a heavy underdog due to his career record of 2-25 against the Serb. On the other half of the draw, two-time champion Murray, 30, plays 24th-seeded American Sam Querrey, who has never been to a major semifinal. Djokovic described the court quality "as not that great. He was not very pleased to see that", Djokovic told British broadcaster BBC after the match.
