Rafael Nadal kept winning the hard way at the Paris Masters on Thursday, overcoming fellow Spaniard Tommy Robredo 6-3 3-6 7-5 to reach the quarter-finals.

Nadal, who saved five match points before taming Nicolas Almagro in another all-Spanish battle on Wednesday, needed two hours and 20 minutes to shrug off a brave challenge from Robredo, seeded 14th in the indoor event.

"I didn't play my best but I played better than yesterday and managed to play big rallies without making mistakes, so that's positive," Nadal said.

Robredo had his chances, serving for the match in the third set, leading 5-4, but Nadal lived up to his reputation as a fierce competitor to recover and seal victory.

Roger Federer's second-round exit in the French capital on Wednesday means Nadal stands an outside chance of finishing the year as world number one.

Before contemplating that accolade he must beat defending Paris Masters champion Jo-Wilfried Tsonga, the world number nine, who swept aside fellow Frenchman Gilles Simon 6-2 6-3.

"The conditions will be good for him with a fast court and the crowd on his side," Nadal said. "He will be the favourite but I'll do my best."

TIRED MURRAY

France will have two players in the quarter-finals for the first time since 1992 after 15th seed Gael Monfils posted a 6-4 6-3 win over Julien Benneteau, who looked exhausted after his shock victory over Federer in the previous round.

Britain's world number four Andy Murray looked tired, too, when he lost 1-6 6-3 6-4 to Czech Radek Stepanek.
