Serena Williams has her sights set on another "Serena Slam" following her demolition of Dinara Safina in Melbourne.

The new Australian Open champion Williams thrashed the Russian 6-0 6-3 in 59 minutes in Rod Laver Arena on Saturday night to win her fourth Australian Open title, 10th grand slam overall and reclaim the number one spot in the rankings.

The 27-year-old American is now halfway towards repeating her slam of 2002-03, when she last held all four grand slam titles, having won the US Open in New York last September.

"The Serena Slam is something I'd like to do again," Williams said.

"It would be great to win more than one, more than two grand slams this year, more than three. That would be awesome."

Next on the list will be the French Open, which starts on May 25.

At Roland Garros last year she bowed out in the third round to Katarina Srebotnik.

"Obviously my sights are on doing well in Paris," she added.

"I didn't do well at all last year. So when I get there I won't have that much to lose and I'll just be really relaxed."

Williams' crushing win on Saturday night saw her join an elite group of Billie Jean King, Chris Evert, Helen Wills Moody, Steffi Graf and Margaret Court who have all won 10 or more grand slams.

But having reached double figures and become the highest female prize money earner in sport, Williams reckons she has plenty left in her.

"I definitely feel like I have so many years to play. Obviously I think I'm playing pretty well, so... I think that I can definitely do it."

Williams took charge of the one-sided final from the first ball as Safina wilted under the pressure of trying to win her maiden grand slam and take the number one spot.

The American second seed, who also won the women's doubles at Melbourne Park with sister Venus, rated her performance as almost on a par with her crushing 6-1 6-2 win against another Russian - Maria Sharapova - in 2007.

"I think '07 and '09 are really close. I don't know which one was really better. I was really playing well in '07, the final," she said.

"I definitely think it was one of my most dominant performances, especially considering it was a final."

Safina admitted nerves had got the better of her once she stepped onto court.

It showed immediately as she double faulted three times in her opening service game to hand Williams the advantage and from there it was all downhill for the Russian third seed.

She managed to hold serve just twice in the 59-minute match, and break the Williams serve once, but Safina, who lost to Ana Ivanovic in the final at Roland Garros last year, was confident she would bounce back quickly.

"If I would lose the first round, of course I would sit here and I would start to think," she said.

"But I lost in the final. I made it all the way. There is much more positive than negative.

"I just lost the match, and now it's back to training. I don't see any reason to panic."
