No. 7 seed Novak Djokovic is back in action early Sunday morning at the 2025 Australian Open with a fourth-round match against Jiri Lehecka.

Novak Djokovic and Andy Murray faced each other 36 times throughout their tennis careers, mostly in finals and often at the business end of a grand slam. But at this year’s Australian Open, their decades-long rivalry has taken an unexpected turn.
