The 34-year-old superstar, who has just won Wimbledon, previously said he was “50-50” when asked if he’d be competing at this summer’s Olympic Games in Tokyo, Japan. But Djokovic, who claimed a record-equalling 20th men's Grand Slam with his Wimbledon win, now says he’s “proudly” joining team Serbia to compete.
Taking to Twitter he said: "I booked my flight for Tokyo."
After retaining his Wimbledon crown Djokovic previously said he was undecided about appearing at the Tokyo Games, particularly after it was announced fans would be unable to attend owing to an increase in coronavirus infections.
The Olympics however will offer him the chance to make history. Having won his third title of the year at the All England Club, he is on course to try to complete tennis' 'Golden Slam'.
He would need to win gold at the Tokyo Olympics as well as taking the US Open singles title in September in order to become the first male player to achieve the feat. The only tennis player to have ever achieved it before is Steffi Graf who did so in 1988.
British number ones Johanna Konta and Dan Evans have already withdrawn from the Games because of positive Covid-19 tests, with Swiss legend Roger Federer, who following defeat at Wimbledon suggested we might have seen his final appearance at the iconic tournament, also pulling out.
Australia's world number 17 Alex de Minaur has also tested positive for Covid-19 and has withdrawn.
Last week it was announced Japan has declared a state of emergency in Tokyo which will run throughout the Olympic Games. It's due to rising coronavirus infections in the city.
Japan's Prime Minister Yoshihide Suga said it would remain in place until 22 August, but he did not give details on the restrictions.
