Rafael Nadal admits it would be "more than perfect" if he could lift the Wimbledon title to go with a Spanish triumph at Euro 2008.

Nadal has been tipped by five-time champion Bjorn Borg to win at the All England Club this year, ending Roger Federer's five-year winning streak in the process.

But while Nadal is 100 per cent confident in the abilities of Luis Aragones' side ahead of their quarter-final showdown with Italy, the 22-year-old from Mallorca admits Federer remains the favourite in SW19.

"We are going to win this year, no doubts," the four-time French Open champion said when asked about the European Championships. "It would be more than perfect if I could win Wimbledon too."

Nadal dismissed suggestions that Federer was more vulnerable on grass this year than previously - the reigning Wimbledon champion's victory in the warm-up tournament in Germany extended the Swiss star's unbeaten record on grass to 59 matches.

However, at the same time Nadal was winning his first grass-court title at the Artois Championships at Queen's Club in London.

And the king of clay pushed Federer to the wire in last year's epic five-set Wimbledon final.

Nadal made it home to Mallorca for a much-need rest after Queen's, and in time to watch Tiger Woods' remarkable US Open victory.

And the Spanish star, himself a keen golfer who partnered Sergio Garcia in a pro-am on the European Tour last year, revealed Woods is now his sporting idol.

"Tiger is probably my idol," Nadal said. "I never have an idol but he is probably the sportsman who I admire more because I like a lot his mentality.

"I like a lot his eyes when he's going to have the important shot. He is always playing with unbelievable determination in important moments. The last part of the fourth day, only one guy with unbelievable concentration, unbelievable determination and big confidence in yourself. Only Tiger can do something like this.

"I know how tough it is playing having pain, and it is very difficult to have very good concentration when you are, in my case, running or touching the ball and you feel pain. That's unbelievable to win a US Open like this."

Nadal's victory at Queen's was all the more impressive as it came courtesy of victories over the likes of Ivo Karlovic, four-time champion Andy Roddick and Novak Djokovic, three of the most likely contenders at Wimbledon.

Roddick was not at his best having missed the French Open with a shoulder injury, but the two-time Wimbledon finalist was unstinting in his praise of Nadal.

"He's playing well, there's no doubt about that," Roddick said. "I think grass helps his serve a lot, probably more so than a hard court.

"I didn't feel sharp. I felt like I was hanging on from the beginning of that match. I hadn't really played much. I went into that one probably knowing it was going to be an uphill battle with how match-sharp he was.

"He feels comfortable on the surface. He's able to create big shots from odd angles, which you get a lot on this surface as well. Everyone acts surprised he's playing well on grass but he made the Wimbledon final the last two years, so I'm not really that surprised."

Djokovic has taken enormous confidence from his Australian Open victory in January and believes Federer is finally feeling the pressure from himself and Nadal.

"You know, quite some things have changed this year," Djokovic said. "It's becoming more interesting to see some new names, new faces winning the major titles, and believing more that they can win against the top players, which makes the game more interesting, of course.

"Roger is still the number one player of the world. He had good results this year but not as good as in the past four or five years when he was really dominant in the sport.

"And mentally he was filled up from such a dominance. It's normal to have ups and downs and he's feeling the pressure a little bit. I think for him it's a big challenge to defend the first place in the world."
