His long-time rival, Roger Federer, was one of the first people to congratulate him and hailed his incredible 13th title at Roland Garros as "one of the greatest achievements in sport".
"I'm aiming to achieve many things this year at both a personal and collective level," Coutinho told a virtual news conference on Saturday. "I can say that I returned to Spain with a lot of motivation. My desire to work and make things happen in my favor has tripled."
"I am taking it year by year and we have just started a new season: I hope I can last a long time in the national team," he commented.
"We are in a difficult situation and through a low ebb. We trained 20 days before the season kicked off, and many young players didn't partner with me. They said they were afraid of this."
Scaloni confirmed the Albiceleste will be without Paulo Dybala for the match because of a stomach problem, while Sevilla midfielder Marcos Acuna is doubtful with a hamstring injury.
"With the experience I have acquired, I feel like a more complete player who can contribute to the team in whichever situation," he told a virtual press conference.
The duo has never faced each other on the Tour level but had an encounter in junior competitions - with Swiatek knocking out the American to reach the quarterfinals of the 2016 girl's singles tournament also at Roland Garros.
"One month and a half ago if you tell me you're going to have this trophy with you again, I will say, This year will probably be too difficult," said Nadal who arrived in Paris this year without any tuneup tournament win, the first time in his career.
Meanwhile, Angel Romero and Andre Carrillo each scored braces as Paraguay and Peru drew 2-2 in Asuncion.
"We didn't show enough of a tough mentality compared with last game, but made timely adjustments at halftime," Zhang noted.
The fourth seed has yet to play Swiatek on the Tour but encountered with each other on the same stage in the junior competitions four years ago.
