Agnieszka Radwanska, Tim Henman and Gisela Dulko are among the high-profile names to join an all-star line-up of past and current tennis champions to captain teams at the inaugural United Cup.
The United Cup is a new annual mixed team event, played across three Australian cities - Brisbane, Perth and Sydney, set to launch the global tennis season from Thursday 29 December.
In Brisbane, former World No. 2 Radwanska will captain Team Poland in Group B, led by World No.1 Iga Swiatek and World No. 10 Hubert Hurkacz.
In Perth, former World No. 1 doubles player and Australian Open 2011 doubles champion Dulko will lead Team Argentina, who are drawn against Croatia and France in Group F.
Former World No. 4 and Roland Garros champion Iva Majoli will captain Croatia, with players Borna Coric and Donna Vekic to fly the flag for their country.
In Sydney, Tim Henman, who inspired a British tennis revival in the 1990s by becoming the first Briton to reach the men’s semi-finals at Wimbledon in 25 years, will captain Team Great Britain, which includes World No. 14 Cameron Norrie, Daniel Evans and Harriet Dart.
Former World No. 3 doubles player Marc Lopez will oversee Spain, a team featuring Rafael Nadal and Paula Badosa.
Home favourites Australia will also be in Sydney, and will be captained by former World No. 1 and two-time Grand Slam champion Lleyton Hewitt and former World No. 4 and multiple Grand Slam champion Sam Stosur in Group D.
Stosur is one of several high-profile “playing captains” to feature at the United Cup.
Others include Stan Wawrinka as captain of Team Switzerland, and Alexander Bublik overseeing Kazakhstan in the same group in Brisbane.
World No. 28 Grigor Dimitrov will captain Bulgaria while Kirsten Flipkens will captain Belgium and Grand Slam doubles champion Edouard Roger-Vasselin will captain France.
