MELBOURNE, Australia—Achieving yet another record at the Australian Open put Novak Djokovic in a reflective mood, revealing how he thought things might change after he'd clinched that historic 24th major title.

Djokovic played his best two sets “in a while” in a 6–0, 6–0, 6–3 demolition of Adrian Mannarino on Sunday to reach the quarterfinals at a major for the 58th time, equaling Roger Federer’s Grand Slam record.
