The ATP Cup is set to take place just before the Australian Open after moving from its scheduled January dates. Debuting in 2020 with Serbia taking the inaugural title, the team event has replaced the Hopman Cup (which featured both men and women).
Once again, the field is led by the top names including Novak Djokovic, Rafael Nadal and Dominic Thiem. Twelve countries have qualified for the tournament with Serbia looking to defend its title.
