ANDY MURRAY admitted to some first-night nerves after taking care of Argentinian lucky loser Facundo Arguello at Roland Garros.

The Scot came through by a 6-3, 6-3, 6-1 scoreline against the 22-year-old world No.137, but said he had battled his own anxiety as well as on-court conditions on Philippe Chatrier, which were cool and windy.

"I was nervous today," he said. "And it was quite windy conditions. But I don't mind nerves because it shows that you care. I hope to play better as the tournament goes on.

"I would hope that it's always there," added the Scot, who surrendered his serve during the first set, but played better the longer the match went on.

"I think almost every time I played in a slam the first round I have felt nervous. It's also quite a long build-up, which we don't have at loads of the other events. Also, these are the tournaments that you really want to perform well in. So, at the start of the tournament it is always normal to be a little bit nervous."

The world No.3 has now won his last 11 clay-court matches and goes on to face either Joao Sousa of Portugal or Vasek Pospisil of Canada in the next round, in a match which will be played on Thursday.

With his pregnant French coach Amelie Mauresmo sitting in the stands alongside his new wife Kim, Murray received a warm welcome and said he hoped that having a Parisian in his corner was boosting his local popularity.

"Well, I mean, obviously today was my first match, so not 100 per cent sure, I guess," he said. "The biggest test is if I play against a French player. They obviously give great support to the French players here. But, yeah, if my connection with Amelie helps, then that's great for me."

Murray is one of three Brits remaining in the singles competition, being joined in the second round by Heather Watson, a 6-4, 7-5 winner against Mathilde Johansson of France, and Kyle Edmund, who became the first British player outside of Murray to win a men's singles match since Tim Henman in 2006 when he won his first-ever five-set match by a 2-6, 6-4, 6-3, 5-7, 6-2 scoreline

The Scot said he enjoyed assuming the role of mentor to the next generation - because he remembered the veteran players who weren't so obliging to him back in the day.

"I was very grateful to all of the players that were nice to me when I first came on the tour, because it can be tough. It's not easy, you know, 17, 18-year-old coming into a locker room with older guys or people that you've watched on the TV and look up to. Some guys weren't nice.

"And I remember that, too. I would rather try to be one of the guys that the young guys look up to and say he was nice to me when I was coming up."

For all this early success, Arguello said Murray's improvements on clay make him a potential champion here.

"I played very well in the first two sets, but in the third set Murray behaved like a champion," said Arguello. "He has big chances to go on and win the tournament. I think any of the big players can win it, but I think he has improved a lot on clay."
