Khachanov has enjoyed his best ever performance at a Grand Slam at Roland Garros and takes on Dominic Thiem in the quarter-finals today.
The Russian had never previously progressed past the fourth round – having gotten to that stage in both of his last two appearances at the French Open – but was excellent to down Juan Martin del Potro in four sets on Monday.
With that win, the 10th seed guaranteed that he will move into the top 10 of the ATP Rankings for the first time in his career.
The 23-year-old claimed his first ever win against an opponent in the top 10 by beating big-hitting Argentine Del Potro and now takes on world No 4 Thiem, who is a clay-court specialist.
The Austrian overcame Moscow-born Khachanov in 71 minutes on the hard courts at the Paris Masters last year, winning 6-4, 6-1, in their only previous meeting.The pair had been scheduled to go head-to-head yesterday only for rain delays to force play back 24 hours.
But Hantuchova believes the towering Khachanov – who stands at 6ft 6ins – can be a threat to the likes of Roger Federer, Rafael Nadal and Novak Djokovic – having beaten the latter at the Paris Masters last year before his loss to Thiem.

That’s going to be a huge factor and it’s going to favour physically strong guys as he is
“Yeah definitely so,” the French Open pundit said of Khachanov being a danger to the big three.
“I completely agree with what Aranxta Sanchez Vicario said, from now on it’s going to be so much about the weather.
“That’s going to be a huge factor and it’s going to favour physically strong guys as he is.
“We better start talking about him because he’s playing incredible tennis.
Karen Khachanov has never got this far in a Grand Slam before
“You know what, from now on, every single match is so open and anything can happen.
“It’s going to be very interesting how he’s going to deal with his first quarter-final here.”
Previewing his clash, Khachanov said: “I will try to do my best against [Thiem].
“He’s reached at least the semi-finals [four] years in a row, so he’s for sure one of the top guys on clay. But I will try to fight and we’ll see.”
