Laver Cup 2019: Schedule, teams, scoring system and everything you need to know

The competition is named after Australia's Rod Laver, one of the greatest tennis players of all time with 11 Grand Slam titles to his name, eight in the open era. He also won five Davis Cup titles with his country and it is fitting that an elite-level team tournament bears his name.

The Laver Cup was inaugurated in 2017 as an indoor hard-court tournament between teams representing Europe and the rest of the world, partially imitating golf's Ryder Cup with a strong American slant on Team World.

A brand new tournament with an unusual format was always going to need big names to help launch it and the biggest - Roger Federer - was at the heart of its creation: his management company TEAM8 were part of the group that came up with the idea.

Its first edition in Prague was an instant hit with five of the world's top 10 players involved including Federer and great rival Rafael Nadal, playing on the same team. The pictures of the two of them playing doubles together flew around the world to give tennis fans an early Christmas present.

After heading Chicago for last year's event, Federer will be on home soil this time around in Geneva.

Like the Ryder Cup that inspired it, the Laver Cup is spread over three days. The first two days consist of three singles matches followed by a doubles match but the final day has the doubles scheduled first, followed by the three singles matches.

The scoring system is design to ensure no team can win the Laver Cup before the final day's play has begun: on the first day, each match is worth one point; on the second day, each match is worth two points; and on the third day, each match is worth three points.

Friday September 20, midday: Dominic Thiem vs Denis Shapovalov followed by Fabio Fognini vs Jack Sock

Friday September 20, 6pm: Stefanos Tsitsipas vs Taylor Fritz followed by Roger Federer & Alexander Zverev vs Denis Shapovalov & Jack Sock

Saturday September 21, midday: Match 5 (singles), Match 6 (singles)

Saturday September 21, 6pm: Match 7 (singles), Match 8 (doubles)

Sunday September 22, 11am: Match 9 (doubles), Match 10 (singles), Match 11 (singles), Match 12 (singles)

If scores are level, a final doubles match will be played to decide a winner.

For the third year running, Team Europe will be led by Bjorn Borg and Team World will be lead by John McEnroe.

2017: Team Europe 15-8 Team World

Appropriately enough, Roger Federer is the most successful Laver Cup player over its first two years with 12 points overall and an unbeaten record (4-0) in singles matches.

The best doubles player is Jack Sock, who has only been beaten once in the format and has also played more matches (8) than anyone else in Laver Cup tennis.
