Murray not underestimating Chela

Andy Murray insists he will not underestimate Juan Ignacio Chela when the pair meet in the French Open second round this afternoon - despite dominating their last five meetings.

Murray has not dropped a set against the Argentinian in any of those victories, including in the first round of this tournament 12 months ago.

But after coming through a five-set epic against Richard Gasquet in round one this year, fatigue and a congenital knee problem could remove any advantage the fourth seed might otherwise have had.

Murray said of his 30-year-old opponent, the world number 54: "He's a very good player. He's obviously got a lot of experience.

"I just need to make sure I recover well. If I feel good going into the match then I'll be confident that I can win.

"But he can't be underestimated with the results he's had, not only here, but on a lot of the clay-court surfaces during his career."

Murray's serve was well below its best against Gasquet but he believes it is his returning game that he will have to improve if he is to make light work of Chela today.

"In a five-set match, if I can lose serve three or four times, I normally bet on myself to return," he said.

"I would love to serve better, but it's the return game that's more important to me.

"I'll try to start the next match better. But sometimes guys can play great tennis."

Despite the drama of his victory over Gasquet, Murray's match today was relegated to third on Court One.

The Scot's vanquished opponent has warned Chela he is in for a tough time.

Gasquet said of Murray: "I think he can play a better game, but he is always fighting.

"He's one of the best players in the world, so you know to beat him - even if not playing his best level - is very hard.

"He knows what to do when the point is really important."

Murray is the only Briton left in the tournament after Katie O'Brien completed a hat-trick of female first-round exits with a battling 6-0 4-6 6-2 defeat to Jill Craybas.

Day three at Roland Garros was meant to be about Justine Henin's long-awaited return to the event after ending her 18-month retirement.

But the four-time champion ended up being upstaged by a 39-year-old from Japan, who had hung up her racquet for 12 years before resuming her career.

Kimiko Date-Krumm produced undoubtedly the biggest upset of the tournament so far with a 3-6 6-4 7-5 victory over Dinara Safina, the former world number one who had been runner-up in the tournament for the last two years.

Henin also won her first match at Roland Garros since completing a hat-trick of title wins in 2007, while Rafael Nadal started his latest French Open winning streak following his first ever defeat there last year.

As well as Murray, today's highlights include defending men's champion Roger Federer v Alejandro Fallo, and Venus Williams v Arantxa Parra Santonja.
