Team Serbia will return to defend its crown in 2021. The inaugural ATP Cup champions, which beat Team Spain 2-1 in last year’s final, will be led by World No. 1 Novak Djokovic. The 33-year-old won all eight matches he contested at last year’s event, including six singles encounters.
Djokovic will be joined in Melbourne by fellow 2020 team members Dusan Lajovic and Nikola Cacic. Lajovic won four of his six singles matches en route to the trophy last year. Filip Krajinovic will make his ATP Cup debut.
