We are doing well.' Is reaching the US Open final more special than winning Davis Cup in 2016?
The Argentine will face either Novak Djokovic, the 2011 and 2015 victor, or Japan's Kei Nishikori in Sunday's final. "I'm here now", he said after advancing when defending champion Rafael Nadal quit after two sets in their semifinal because of right knee tendinitis.
Whether he beats Novak Djokovic on Sunday to claim his second grand slam title or not, Juan Martin del Potro will still consider himself a victor.
All four players have reached the U.S. Open final - only Nishikori hasn't won it. Del Potro, like Wawrinka, can become a risky opponent if he builds up some momentum and can draw the match into becoming a slug-fest from the baseline.
Rafael Nadal retired from his U.S. Open semifinal with right knee pain that has dogged him on and off for years, sending Juan Martin del Potro into Sunday's final.
"I don't have a great record against Novak, but always it's been a tough match the last couple of years".
"One of the keys of the match will be [my] return, how well I can return, how many returns I can get back in play, but also try to have some depth in that return, and how accurately I can serve myself".
One of the greatest players of all time, the one chink in the Spaniard's armour has always been his knees with injuries plaguing him throughout his career.
Now they are set to face each other on Sunday for the first time in a grand slam final on the biggest stage in tennis, the US Open in NY.

"I never go onto the pitch with the intention of injuring another professional so I have a very clear conscience", Ramos said. Enrique appears to be concentrating on bringing the players closer and building greater camaraderie within the group.
"I think it was 2-2 in the first, 15-0, that I felt it". "But I think that is completely in the past, and now I'm having a good present, looking forward for the future".
"I hate to retire", said Nadal who has endured a series of knee injuries throughout his career. "He's a dear friend, someone that I respect a lot".
"Of course, it's not the best way to win a match", said del Potro, who hugged Nadal when it was over. But, you know, he's got two days now to recover, so he's going to be fresh.
"I didn't know if I (would) be a tennis player again or not".
Nadal eventually won in five sets but it took all his enormous powers to repel the lethal Del Potro forehand after nearly five hours.
"I didn't know if I will be a tennis player again or not".
And he will start the heavy favourite, boasting a 14-4 record over the Argentine who will be playing in just his second final at the Slams. He was also made to work hard for his Round of 16 win over Karen Khachanov that came in four sets on a similarly energy-sapping evening in the city.
Djokovic went into cruise control in the third set, winning four consecutive games from 2-2 to win the match and book his spot in the final.
