Nick Kyrgios returns to the French Open next week after a great debut there last year.

An invaluable training week with the great Roger Federer - where he even took a set off the Swiss maestro - has rising Australian tennis star Nick Kyrgios buzzing ahead of the French Open.

The 19-year-old from Canberra will return to the scene of his breakthrough victory after receiving a wildcard into the main draw at Roland Garros for the year's second major starting on Monday.

It was this time 12 months ago that Kyrgios burst into the senior ranks with a stunning first-round upset over former world No 8 Radek Stepanek.

Kyrgios admitted that last year he was too nervous to share a locker room with 17-time Grand Slam champion Federer.

Speaking from Paris on Monday night, the big-serving 193-centimetre teenager confidently said he ''was holding his own'' during a recent practice session.

"I was serving for the set against him and got a bit nervous and he broke me back. I was definitely feeling pressure against him even though it's only practice,'' Kyrgios said.

"I thought that he might not have been giving everything in every point but I thought I was holding my own out there.

"It was a lot of fun to see him go to work and his ability to get some hard training done even though he's accomplished so much.''

Kyrgios won back-to-back clay court challenger tournaments in the US earlier this year after missing a couple of months with an elbow injury.

He was forced to retire from the qualifiers of an ATP event in Dusseldorf last week because of shoulder soreness, but was confident he would be close to full fitness for the French Open.

"I've still got a full week, so at this stage I would say I would be near 100 per cent going into it,'' Kyrgios said.

"My shoulder is feeling fine, it was just precautionary, so I'm just getting my best preparation (for the French Open).''

Kyrgios has set a goal of again progressing to at least the second round at Roland Garros, and is putting all of his focus on the singles.

"Coming here again, after having pretty good success last year, is an experience I'm not going to forget,'' Kyrgios said.

'''I called it a mini-breakthrough because I had some success after that.

''I learnt a lot of things after that match that I've learnt and improved in many areas.''

Kyrgios is currently ranked 161 in the world and has been touted by many, including French veteran Richard Gasquet, as a future top 10 prospect.

He became the first Australian since Peter Luczak in 2009 to win an ATP clay court challenger when he won in Sarasota in April, backing it up the following week with victory in Savannah.

"I think my game suits (the clay) well and I enjoy playing on it,'' Kyrgios said.

"The rallies are extended and you get those long points.

''Sometimes they finish with something pretty crazy, but I've played some really good matches on clay.

"I've played Davis Cup and had some really good results against some really good players on it.''
