US Open - John McEnroe says Nick Kyrgios retiring is 'not impossible, adds he has ‘one of the great serves in history’

Former US Open champion John McEnroe has hailed Australian star Nick Kyrgios as playing the best tennis he’s ever played, but did warn that is “not impossible” that he could walk away from the sport after the US Open. Kyrgios, 27, produced one of the performances of his career as he beat number one seed Daniil Medvedev in four sets on Sunday evening, in what was one of the games of the tournament. Ad Speaking afterwards Kyrgios made vague comments about this being the end of his journey in tennis, which led to intense speculation about his future.

«It's the last biggest tournament of the year,» he said. «We've got to try and just tough it out and keep pushing each other, keep being positive. Next week we're going home.

But three more matches potentially, then we never have to play tennis again.» US Open‘You absolute pelican’ – Reliving Kyrgios and Khachanov’s Twitter spat ahead of US Open meeting4 HOURS AGO Speaking with Barbara Schett on the Eurosport pre-show ahead of Monday’s action, McEnroe said: “Well I've got some bad news for you. Ash Barty [retired after winning a major], so it’s not impossible to think that he could do that. “We hope he won't do that because there’s a phrase, I think it’s worldwide — ‘better late than never’.

That applies to Nick, because he wasn’t professional for a long time, he played a lot of matches where he wasn’t giving it his all, and now you see what he’s capable of when he does. And he trains and he’s in shape and the guy’s phenomenal.” McEnroe, who won at Flushing Meadows four times as a player, was also full of praise for Kyrgios’ serve, hailing as one of the best the game has ever seen. ‘You absolute pelican’ – Reliving Kyrgios and Khachanov’s Twitter spat ahead of US Open meeting
