The event is scheduled to be held at the United Center from tomorrow through till Sunday (September 23).

Twenty-time Grand Slam champion Roger Federer of Switzerland is once again joined on the blue side by Germany’s Alexander Zverev as well as newcomers Grigor Dimitrov of Bulgaria, David Goffin of Belgium, Kyle Edmund of Great Britain and 14-time major winner Novak Djokovic of Serbia.

"At the Laver Cup we’re a team," Federer said.

"That’s exciting and something we’re not used to.

"To be on the same team as these legends - and legends in the making - and to spend a week getting to know these guys, is a wonderful way to celebrate tennis."

Attempting to put last year’s disappointment behind them and claim the Laver Cup for Team World will be American trio John Isner, Jack Sock and Frances Tiafoe as well as Australia’s Nick Kyrgios, South Africa’s Kevin Anderson and Argentina’s Diego Schwartzman.

Anderson and Schwartzman are the new additions to the red side.

Led by Björn Borg and John McEnroe, the captains of Team Europe and Team World respectively, the two line-ups attended a player welcome ceremony yesterday at the iconic Pritzker Pavilion.

Joining them was Rod Laver, the winner of two calendar Grand Slams in 1962 and 1969, and the man whose achievements have been honoured by the creation of the Laver Cup.

"I’m honoured that my name is associated with this trophy," the Australian said.

"It’s also a thrill to have the Laver Cup here in Chicago.

"You’ll see some wonderful tennis and a lot of camaraderie."

In total, there will be nine singles matches and three doubles contests held.

Both singles and doubles are best-of-three sets with advantage scoring.

In the event of split sets, the third set is a 10-point match tie-breaker.

Each match win will be worth one point tomorrow, two points on Saturday (September 22), and three points on Sunday (September 23).

If the scores are tied at 12-all on day three, a doubles set with a tie-breaker will decide the Laver Cup champion.

The winning team must reach 13 points.

An exhibition match will be played after the trophy ceremony if the overall winner is decided after match nine.

"I’m very much looking forward to coaching this team," McEnroe, sitting alongside his younger brother and Team World vice-captain Patrick, said.

"We’re excited about getting the home-court advantage, hopefully, in Chicago.

"It’s a great sports town and we’re looking forward to showcasing our talents here this weekend."

Borg, flanked by vice-captain and fellow Swede Thomas Enqvist, added: "Last year there was some unbelievable tennis played in Prague, we had a lot of fun and for me to spend a little time with these great players for a week was unbelievable.

"It was a very close match, and this weekend I think there is going to be some great tennis and tight matches.

"But one thing I agree with John on is we are here to defend our title, and we’re going to keep the Cup in Europe."
