A despondent Alexander Zverev questioned if he was “good enough” to win a grand slam title as Jannik Sinner won a second Australian Open in a row with a dominant straight-sets win in Melbourne.
Zverev was left to admit that World No 1 Sinner is in a “different universe” at the hard-court grand slams after the Italian won a third consecutive major on the surface with a ruthless 6-3 7-6 (4) 6-3 victory.
