Medvedev also sees an edge in having faced Nadal in Canada, even in defeat.
"Long because I've played so many matches", said Medvedev.
Federer holds the all-time men's record of 20 grand slams and at 38 his opportunities to win another are waning, making the two match points the Swiss great squandered against Novak Djokovic in the this year's Wimbledon final all the harder to bear. Sunday is one. It's just one more chance, that's all.
Medvedev has been ridiculously good on hard court this year and has proven that he's capable of playing with the best in the world.
Nadal, who is into his 27th major final, defeated Medvedev in the final to triumph at the Rogers Cup last month, and then the Russian bounced back to lift the trophy at the Cincinnati Masters.More news: IPhone 11 Pro vs Samsung Galaxy S10
Those emotions are echoed by former world number two Alex Corretja, who claims that a "tired" Medvedev will find it hard to keep up with the relentless Rafa. "I think it's okay".
Reaching the last two in this competition is just reward for another excellent U.S. hard court season for the Russian, who has reached the final of all four major tournaments played this summer - Washington, Montreal, Cincinnati, and now NY - only the third man to achieve that feat.
However, Medvedev's fitness has been a matter of considerable debate throughout the tournament and for around a week now, I've issued the same, consistent, mantra "there is no concrete statistical evidence that Medvedev is hugely hampered by his perceived injury".
"What sustains you, I don't know", he said. "He kind of, I would say, (ate) me on the court because the start was kind of similar".
"I would love to be the one to have more, yes, but you can not be all day frustrated or all day thinking about what your neighbor has better than you", the 33-year-old Spaniard said after reaching the U.S. Open final to give himself a shot at another major championship.
NADAL POWERS THROUGH In the second semifinal, Nadal, the three-time US Open victor, punched 37 winners to claim a 7-6 (8-6), 6-4, 6-1 win in 2 hours and 35-minutes over first-time major semifinalist Italy's Matteo Berrettini.More news: PM Johnson vows to get Brexit deal after losing election vote again
Berrettini raced out to a 4-0 lead thanks to some uncharacteristically sloppy play from the Spaniard and the 23-year-old had two set points at 4-6.
Nadal flicked a forehand passing shot that dipped enough to make Berrettini's volley try rather tough, and the ball found the net.
"I was lucky to win that first set", Nadal said. "I won a lot of four-set matches, which shows how great mentally I was here, and physically, also".
"You don't want to be in a tiebreak against a player like Matteo".
Nadal saved two set points in his first-set tie-break against Berrettini, and was mightily relieved to push on and win the second semi-final 7-6 (6), 6-4, 6-1. In their match, the missed attempt gave Nadal the point that leveled the tally at the second change of ends and he grabbed the next two points for the set. "Another final of the Grand Slam, and another final here in Flushing Meadows means a lot to me". The Flushing crowd, which booed Medvedev earlier in the tournament for raising his middle finger at the fans, has grown to appreciate his artistry.
After reaching his first Grand Slam final with a straight sets victory over Grigor Dimitrov on Friday, it is unlikely anyone will make that mistake again. "It's really unusual. I think this year before I've played like three lefties in all the year", Medvedev said. "I think after, I was playing better than him". "We had some unbelievable level".More news: Wendy's to add breakfast including Frosty cappuccinos, honey butter chicken biscuits
In the second set, Dimitrov was up 40-30 on his serve in the tenth game but was taken to deuce. Medvedev broke for a 3-1 lead in the third set and held to the finish.
