Davis Cup captain Lleyton Hewitt believes Nick Kyrgios can go deep into the tournament at Roland Garros.
Kyrgios, currently ranked 16 in the world, has been in career best form, defeating the likes of Roger Federer and Novak Djokovic earlier this year.
Hewitt believes he can cause even more upsets at the French Open next month and possibly even go close to winning the title.
"He can do well, especially with where his ranking's at at the moment. He's going to be a nice seeding going into the French," Hewitt said on the RSN Breakfast Club.
"You've always got to be wary of dangerous floaters at the French Open because there's so many good claycourters, especially from Europe.
"So in some of those early rounds, he's got to be wary and pay that respect to those opponents, but he could easily get through to the fourth round and the the draw opens up and all of a sudden you're deep into the second week."
Kyrgios, who turns 22 today, has been touted as a future grand slam since bursting onto the scene, but has battled with the mental side of the game.
However, following a controversial five-set loss to Andreas Seppi at the Australian Open, Kyrgios seems to have beaten many of those mental demons, winning six of 18 matches since the first slam of the year and Hewitt says his game can beat anyone on his day.
"He's got so much firepower that if he's serving well he's still able to serve through a slow clay court and get a lot of cheap points," Hewitt said.
"And then he can go out and actually be quite aggressive on his return game and put pressure on his opponents."
Roland Garros kicks off on May 28.
