The Laver Cup pits six players from Europe against six players from the rest of the world against one another in a Ryder Cup-style tournament. 

This is the fourth edition of the competition, with Team Europe, who are led by Björn Borg, having won the first three.

Borg's great playing rival, American John McEnroe, will lead Team World for the fourth time, hoping to end his wretched run against the Swede.

Team Europe features six top-10 ranked players in the world, with every single player currently ranked higher in the world than the highest-ranked player from Team World.

Medvedev of Russia is currently ranked second in the world and will be full of confidence having secured his maiden Grand Slam title.

He is joined by Germany's Olympic champion Alexander Zverev, compatriot Reblev, Greece's Stefanos Tsitsipas, who has recently copped for controversy with his vaccination stance, Matteo Berrettini of Italy, and Norway's Casper Ruud.

Team World is led by Canadian's pair Denis Shapovalov, Felix Auger-Aliassime, who are ranked 12th and 11th respectively.

Americans John Isner and Reilly Opelka, Australian Nick Kyrgios, who has dropped to 95 in the world rankings though could be a fascinating wildcard, and Argentina's Diego Schwartzman complete the line-up.

The Laver Cup will be contested over the next three days.

On each day, three singles matches and one doubles match will be played, with no player allowed to play more than two singles matches across the three days and every player playing at least one singles match.

Each match on day one earns one point, on day two earns two points and day three, three points.

The first team to 13 points wins, with one final doubles match required if it is 12-12 after the 12 matches.
