Tennis' innovative new team championship kicks off the men's 2020 season on Friday, with Rafael Nadal and Novak Djokovic among those looking for a winning start ahead of the first Grand Slam of the year.
The ATP Cup will see 24 nations split into six groups across three Australian cities, with eight teams emerging from the round-robin to compete in a knockout phase until one country is left standing. It is the sport's newest tournament and the third men's team event competing for the hearts and minds, and dollars, of fans, along with a revamped Davis Cup and the annual Laver Cup, which pits Europe against the World.
