Rafael Nadal is one win away from a 16th Grand Slam title and third at the U.S. Open.
The Argentine has had an injury-ravaged few years since that win but after a five-set victory over rising Austrian star Dominic Thiem and a four-set win over Federer, he is ready for the challenge against the world No.1.
Despite some injuries in the recent years, "I have had an wonderful season", said the 31-year old Spanish player.
"I have the passion to play with full energy, and to come back here many years". I will have the chance to play against him in the semi-finals in my best tournament and just try to think about tennis.
"I was playing too much to his backhand and I knew that I had to change and move him more and be more unpredictable". Will Del Potro break through to make just his second Grand Slam final or will Nadal find a way to compete for a third US Open title?
"When he's playing well it's hard to stop him", Nadal said. He's a huge player with an unbelievable serve and he plays so well on these kinds of surfaces.
Nadal, the overwhelming favourite, has no intention to underestimate Anderson, the lowest-ranked US Open finalist since the ATP rankings began in 1973.
This is the 23rd Grand Final of Nadal's career.
Nadal has not been as dominant in NY as he was at the French Open, which he won for the 10th time and without dropping a set, but the world number one has played himself into sparkling form.
Nadal emerged triumphant in 2010 and 2013 while losing to Djokovic 6-2, 6-4, 6-7 (3-7), 6-1 in the final of the 2011 edition. More important, (I) have given myself a shot at being in the finals and I will be playing for a Grand Slam trophy. "I am in the semi-finals".
Juan Martin Del Potro has done it once so why can't he do it again? Eeasing past all unseeded players so far in the tournament, Nadal now is up against the man who had defeated him at a similar stage eight years back.
"Today was the day to play the best match of the tournament since that moment, because I gonna play against the toughest opponent in that moment, and that opponent, as I said before, coming with big confidence", said the two-time champion.
