Roger Federer and Rafael Nadal are planning on teaming up to play doubles in next year's inaugural Laver Cup.
The pair have confirmed their places in the event, which has taken inspiration from golf's Ryder Cup.
According to The AP, Federer and Nadal, who have 31 Grand Slam titles between them, plan to join together for the tournament, which will pit European players against a team from the rest of the world.
Bjorn Borg has been named the captain for Europe, while John McEnroe will take charge of the rest of the world team.
The event - named after Australian tennis great Rod Laver - will run from September 22 to 24 next year in Prague.
