Serbia's tennis icon Novak Djokovic stormed into the semi-finals of the men's singles event after mounting a memorable comeback against Stefanos Tsitsipas at the ongoing Paris Olympics.

Djokovic kept hopes of his first Olympic gold alive after securing a 6-3, 7-6 win over Tsitsipas in the quarter-finals. In the second set, he was visibly in discomfort and called the physio twice for his right knee.
