Long-time tennis rivals Roger Federer and Rafael Nadal will team up for the Laver Cup, playing side by side in a Ryder Cup golf style event.
This competition will see the world No 1 Nadal and 19-time Grand Slam champion Federer play for Team Europe against a Rest of the World side in Prague.
With four Grand Slam titles between these two legends this year, it will be their first appearance on the same side of the court AFP reports.
Nadal sealed a 10th title win at the French Open and a third at the US Open whereas Federer seized the Australian Open and Wimbledon titles.
After the announcement of the Laver Cup teams, Skysports cites Federer saying: "After all these years I actually get a chance to support his forehand, his aggressive play, his fighting spirit, his everything.
"He's been a wonderful champion for our sport.
“I think Rafa brought something to the game that we really haven't seen that much before, or not at all. The amount of spin he was able to bring to the game or the physicality and his movement on clay."
Meanwhile, Nadal mentioned, "I've never seen anybody with all the ingredients that Roger has. Big serve, big forehand, movement, the slice, but at the same time he plays with unbelievable elegance."
Joining Federer and Nadal in the Europe team are: Marin Cilic, Alexander Zverev, Dominic Thiem with former number four Tomas Berdych making up the squad.
Team World, skippered by John McEnroe, features four Americans -- Frances Tiafoe, Sam Querrey, John Isner and Jack Sock as well as Australian crowd puller Nick Kyrgios and Canadian teenager Denis Shapovalov, AFP adds.
