McEnroe on Sinner: "This title in Melbourne shows the considerable margin he has".

Last week, Jannik Sinner won the Australian Open for the second time in succession. The Italian, world number 1, dominated Alexander Zverev, his runner-up in the rankings, in three short sets.

During the tournament, Sinner didn't always play at his best, and was affected by the heat in his round-of-16 match against Holger Rune.

Nevertheless, Sinner confirmed that he has been the best player in the world since the beginning of last year. On Eurosport, John McEnroe praised Jannik Sinner.

"You have to give credit to Novak Djokovic and Carlos Alcaraz for pushing Sinner to give even more of himself in training and to improve.

Nevertheless, this title in Melbourne demonstrates to the whole circuit the considerable margin that the current world number 1 still possesses.

As well as being the best player in the world today, Sinner is still young and still developing.

He can still improve. I'm convinced he'll work on his approach to the net, his volleying and his serve, too," said the American legend.
