Roger Federer and Rafael Nadal are teaming up again at the 2019 Laver Cup, which starts Friday in Geneva.

“He couldn’t be more pumped up for this event,” Federer said on Wednesday. “He just won the US Open. It would have been so easy for him to say, ‘Look, I need a break.’ But he said, ‘No, my break’s coming afterwards. I push it all aside, and I’m doing this because I really believe in the concept of the Laver Cup. And I believe in you guys.’”

The players were welcomed and made a public appearance on the balcony of the Palais Eynard, Parc des Bastions on Wednesday afternoon ahead of the third edition of the Laver Cup, which pits the best of Team Europe against the best of Team World.

“It’s been energetic, it’s been thrilling, it’s been exciting. The two teams have finally clashed and seen each other. We are all ready to go,” Federer said.

Fans meet the superstars of tennis as Team Europe and Team World are officially welcomed to Geneva for the Laver Cup 2019.

He and Nadal combined forces for Team Europe during the inaugural Laver Cup, in Prague in 2017. The two all-time greats played doubles together, beating Team World members Sam Querrey and Jack Sock 6-4, 1-6, 10-5.

Expect Federer-Nadal to take the court together again as the two practiced doubles together on Wednesday against teammates Alexander Zverev and Fabio Fognini. The team competition gets underway on Friday.

Captains John McEnroe (Team World) and Bjorn Borg (Team Europe) and Rod Laver himself talked with fans and shared selfies before gathering for the welcome meet.

“We’re excited, getting settled in and getting pumped up, just making sure we bring it on Friday, Saturday, Sunday,” said McEnroe.

Borg added: “I’m just happy that Laver Cup has started. We’ve got the team together and everybody is ready to play.”

Team Europe, looking to win the trophy for a third time after victories in Prague and Chicago, enjoys home advantage this year, with Swiss hero Federer and Nadal joined by Dominic Thiem, Alexander Zverev, Stefanos Tsitsipas and Fabio Fognini.

John Isner, Milos Raonic, Nick Kyrgios, Denis Shapovalov, Jack Sock and Taylor Fritz will carry Team World hopes when the action gets under way at Palexpo.

Isner admitted his side is up against possibly “the greatest tennis team of all time” but the American was backing the “powerful players” on Team World to provide a serious challenge.

And if Europe had the edge in terms of results over the first two Laver Cup installments, World have led the way when it comes to celebrations.

“I like their craziness, it’s all good,” said Federer. “I think they’re good guys and they’ve been great the last two Laver Cups, we’ve had a great rivalry. Laver Cup isn’t very old but I feel like it’s all happening, and I’m happy to see all the guys here in my home country.”

“We have such a strong team again this year and I’m very, very happy and excited about the weekend,” added Federer, holder of a record 20 Grand Slam titles. (ATP, Laver Cup)
