Novak Djokovic says he could skip the Olympic Games as Roger Federer did in 2016.
Both, Djokovic and Federer, have never won the singles gold medal.
The pair are expected to represent their national teams at next year’s event in Tokyo.
"There is a chance. For example, Federer did not play in Rio,” Djokovic said. “Our season is long and we are full of new events.
“I will have to be healthy, my appearance in Japan will depend on Wimbledon results, the team schedule and my family.”
