The effervescent Swiss will need to reproduce the kind of all-out attacking tennis that allowed him to dominate Nadal, apart from a 36-minute second-set capitulation.
Down 3-1, Federer all but surrendered the set with half-hearted returns as Nadal levelled the semi up. The last 18 strokes were all crosscourt backhands, with the players remaining in more or less the same position until Djokovic finally switched it up with his shot straight down the line.
Eleven years later, Roger Federer got his revenge.
This was the second major in a row where they've faced off: Nadal won their French Open semifinal last month en route to his 12th championship on the red clay there.
"I had my chances", said Nadal, who offered no excuses for the loss.
That's according to Nadal's coach Carlos Moya, who is confident that Nadal will be pumped up come game time against Federer. Federer serves with a point's lead in the set.
"It was tough. I had spells where I really was serving very well". "But at the same time, I [will] create another opportunity to be in another final of a Grand Slam". Federer ranks first among men with 20 career Grand Slam titles.
"Hopefully I can push him to the brink and beat him, but it's not going to hard".

Djokovic, meanwhile, will be looking to add another Wimbledon title to the Australian and US Open crowns he already holds.
Only five of their last 22 clashes has gone to a final set and very often the victor of these encounters has won it with a bit to spare, so if I were backing either man in match odds on Friday I'd be inclined to risk the -1.5 sets.
The Spaniard won 6-4, 6-4, 6-7 (5/7), 6-7 (8/10), 9-7 as the clock ticked past 9pm and with the famous stadium in near-darkness.
World number one and defending champion Djokovic now stands between the 37-year-old Federer, the oldest finalist at the All England Club since Ken Rosewall in 1974, and a record-equalling ninth Wimbledon title which will also seal a record 21st Grand Slam.
Djokovic has been in fine form, losing only set thus far, to Polish 22 year old Herbert Hurkacz, who provided a stern challenge.
Nadal dug deep to hold, and in the tie-break that followed the Spaniard found the corner to win a remarkable opening point and go the mini-break up. I'm just relieved it's all over at this point.
But Djokovic was relentless and tightened his grip, breaking twice for a 4-1 lead, and eventually claimed victory on a fifth match point.
The victor will advance to the final, where he will face either Djokovic or Bautista Agut.
Nadal then broke again for 5-1 as Federer suffered a sudden and severe power outage with the two-time champion comfortable levelling the contest. He double-faulted on his first set point but converted the second with a volley victor that clipped the net cord.
