On what turned out to be the longest-ever semi-final day at Wimbledon, Anderson still had no idea who he would play in Sunday's final as Djokovic led Nadal by two sets to one when play was halted at 11.02pm on a floodlit Centre Court.
The future is looking beyond bright for Dallas' resident tennis darling John Isner. "Just playing like that in those sort of conditions is really tough on both of us".
Easy or not, Nadal is into the Wimbledon semifinals for the first time in 2011. "I really hope we can look at it and address this because at the end you don't even feel that good out there".
He added: "It's a bit of a sign for the Grand Slams to change this five-set format".
After winning each of his first four matches in less than two hours and 25 minutes, Nadal needed just about double that-four hours and 48 minutes-to take down Juan Martin del Potro in five sets (7-5, 6-7, 4-6, 6-4, 6-4) in the quarterfinals on Wednesday.
South African Anderson eventually overcame Isner to reach the Wimbledon final.
Nadal and Djokovic will meet for the 52nd time.
Having been warmed up by the longest semi-final in The Championships' history, the Centre Court crowd feasted on an excellent display of world-class tennis, lapping up the brilliance of two of the greatest sportsmen of all time under the roof on Friday night.
There were a total of 102 aces in a match with Isner serving 53 aces and Anderson serving 49. Anderson then took the fourth set 6-4, breaking the Isner serve twice in the set.
Tennis writers also took aim at how the officials were quick to reschedule the women's final but stopped short of moving the time of the men's final because of a clash with the World Cup final. He got back to his feet and played a left-handed forehand which landed in before going on to win a crucial point. Both were on clay, in Madrid past year and in Rome as recently as May and the top seed regained his composure in the second set converting two out of three opportunities to break serve and level the last-four contest at one set apiece.
After 6ft 8in Anderson edged the opening tie-break he eked out another break point in the second set, but once again Isner repelled it and this time the tie-break went the way of the American.
The fifth set between Isner and Anderson went for 2 hours, 55 minutes.
Djokovic set himself up to take the first set with strong service games, facing no break points, and broke in the seventh game before sealing it with a forehand victor.
In his last two matches alone, Anderson has been on court for nearly 11 hours. Though Isner does have a bigger serve than the South African, he has less options should it come back.
Isner's 214 aces were the most ever in one Wimbledon, surpassing Goran Ivanisevic's 213 in 2001.
