Federer excited to play with Nadal

Federer opened up about playing alongside Nadal again.

“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 Laver Cup sees the best of Team Europe take on the best of Team World, which features Nick Kyrgios.

“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 after the players came together for promotional purposes on Wednesday.

Kyrgios will be hoping to lead Team World to their first victory after Team Europe prevailed in the first two editions.
