Former British number one Greg Rusedski has revealed that he believes Rafael Nadal’s 11 French Open Grand Slam crowns will never be beaten, according to a report on the Express.

The former player, who is now a pundit for Eurosport, labels Nadal’s achievements in Paris as “superhuman”.

The current world number one coasted to his fourth title of the clay court season by defeating Dominic Thiem in straight sets, although he did look like he was struggling with fatigue in the final few points.

When speaking about Nadal’s astonishing record, Rusedski said:

That is 11 titles, something you will never, ever see in your lifetime again. Eleven Slams, it’s superhuman, it’s Rafael Nadal.

Well done to Rafa, I can see it going 12, 13, 14, 15, 16. Nobody is stopping this man and he’s still so hungry. So, well done Rafa.

The only player on par with Nadal with 11 Grand Slam wins in one tournament is Margaret Court, who won the Australian Open 11 times.

Nadal had already won the Monte Carlo Masters, Barcelona Open and the Italian Open over the last two months and retains his position at the top of the world rankings.

He has cast some doubt over his participation in this year’s Wimbledon but he will be hoping to overcome any problems prior to the prestigious event.
