World number one and four-time Wimbledon victor Djokovic booked his 25th Grand Slam final appearance with a nervy 6-2, 4-6, 6-3, 6-2 triumph over Spain´s 23rd seed Roberto Bautista Agut.
In the men's final, will meet eight-time Wimbledon victor 37-year-old Swiss Roger Federer (3rd racket of the world) and the current holder of the trophy 32-year-old Serb Novak Djokovic (1st).
Djokovic and Nadal hold arguably the greatest rivalry, having met 54 times (with the former leading 28-26) including some of the most gruelling and intense finals in history - namely the 2012 Australian Open final.
"It was a joy to play today", he added after reaching his 31st grand slam final.
The 37-year-old, on the other hand, dropped the first set he played, to unheralded Lloyd Harris in the first round.
There was no rain break, no twilight five-set drama and no Wimbledon trophy on offer on Friday but none of that bothered ageless Swiss maestro Roger Federer.
"He's one of the people that actually made me a better player".
"Age kicks in. I know it's not over yet". Djokovic said, "so to be in another final is a dream come true".
The defending champion came through a tough match against Roberto Bautista Agut on Centre Court 6-2, 4-6, 6-3, 6-2. (That's nearly certainly true.) They insist they want to win Wimbledon for the sake of winning Wimbledon, not as a matter of comparison.
The men's semifinals begin at 1 p.m. local time (8 a.m. ET) when Novak Djokovic plays Roberto Bautista Agut.
Federer broke early in the third and held off break points in the next game.
It's all on the line in their 48th meeting, and Djokovic must shut off the fact he is facing Wimbledon's darling and channel all that energy into lifting a 16th Grand Slam title. It's finals of Wimbledon.
Djokovic, 32, had faced only one seeded player (David Goffin) in breezing to Wimbledon's final four after early-round upsets bounced four top-10 players from his half of the draw.
"I had to dig deep", Djokovic said.
Against expectations, Federer continued to win the baseline exchanges and lengthy rallies, breaking in the third game to edge ever closer to Sunday's showpiece.
The Spaniard's form had led American great John McEnroe to declare: "You play against a guy like Nadal, he wants to tear your heart out". The never-ending GOAT debate is very much a three-man race at this point-Federer, Nadal and Novak Djokovic, of course-so any match pitting two of them against each other, a fairly common recurrence even as all three advance into their 30s, carries weighty historical implications. Even though their overall record stands at a lopsided 24-15, the Swiss leads 2-1 on grass, with all matches played at Wimbledon. "You go through these kinds of emotional moments, especially in big matches like this, all the time".
Rafael Nadal was the oddsmakers favorite, but Roger Federer got past Nadal with unrelenting attacking tennis and impeccable serving.
