Rafael Nadal played down his chances of matching Roger Federer’s Grand Slam haul yesterday, saying the likelihood of reaching his rival’s record of 16 titles remained “a dream.”

After adding four more Grand Slam titles in the past year the 25-year-old Spanish world number one now has 10 to his name and will be targeting an 11th at Wimbledon over the next fortnight.

Victory at the All England Club would see Nadal move alongside Bjorn Borg and Rod Laver in the all-time standings, one behind Roy Emerson on 12, three behind Pete Sampras (14) and five behind Roger Federer.

But Nadal dismissed suggestions that Federer’s record was in his sights, saying he was “very far” from the Swiss master’s benchmark.

“I am not close to the 16 of Roger,” Nadal said.

“Sixteen is a lot. We can dream about a lot of things. For me it’s a dream. Maybe not for you.”

Reigning champion Nadal – who opens the defence of his title with a first round match against American Michael Russell on Centre Court today – enjoyed a stellar 2010, scooping the French, Wimbledon and US Open crowns.

But although Nadal defended his French crown at Roland Garros earlier this month, he doubted whether he would be able to emulate his feats of last season.

“Last year was in my opinion very impossible to repeat – three Grand Slams in a row,” Nadal said.

“I am very happy about what’s going on this season. But I don’t think I will repeat what I did last year for sure.”

Nadal, meanwhile, is already eyeing the defence of his Olympic gold medal next year, when Wimbledon will host the tennis tournament of the 2012 London Games.

“The Olympics are a very special event. The experience that you can live on the village, and, you know, live these moments with the rest of the sports people, that is something special,” Nadal said.
