History beckons for relaxed Serena

Serena Williams says she will treat the US Open just like any other tournament but admitted that she is aware of the historical implications for her at the year's final grand slam.

The six-time winner at Flushing Meadows is the big favourite to win the August 31-September 13 tournament in New York City, and should the world number one claim the title there for a fourth time, she would become the first player since Steffi Graf in 1988 to win the calendar year Grand Slam.

"I don't feel that fresh pressure," the 33-year-old American said on Thursday.

"If I make it far, maybe I'll start to feel pressure. But as of now I really don't feel any. I'm just here to perform and do the best I can.

"At Wimbledon I was going for the second Serena Slam. That is rare. That really gave me the best practice and preparation in terms of going for the Grand Slam."

A victory in the 'Big Apple' would give Williams her seventh US Open title, which would push her past Chris Evert on the Open era list of tournament winners, while drawing level with Graf on 22 grand slam titles. Only Margaret Court – who won the calendar Grand Slam in 1970 – has more grand slam titles, with 24.

"There's always another record, then there's always another person to catch up with or to pass," Williams continued.

Williams credits her coach Patrick Mouratoglou for her remarkable form in the last couple of years, but the world number one refused to be drawn into comparisons with other greats of the game.

"Working with Patrick has helped me a lot and helped me to achieve that consistency and have different goals, change different elements in my game, and also just be overall a better competitor on every single surface and every single match," she added.

"I never really thought I would be in this position where I would even be talking about records, talking about passing Steffi Graf or even mentioning Margaret Court.

"I just grew up trying to be the best that I could. I can sit here and say that I'm the greatest player that I've been able to be. It's really difficult to compare one generation to another.

"I do read numbers and I do see numbers. I believe in those numbers."
