It is four years since the Russian pin-up burst on to the scene as a complete unknown with a fourth-round appearance at the All England Club, followed 12 months later by victory over Serena Williams in the final.

"I've done it before so I can do it again," she said. "Grass definitely suits my game. I think in any grand slam I have a chance - I've been to the final of the Australian Open and just got to the semi-finals of the French - but everywhere you feel comfortable is obviously where you feel you can do well."

She added: "I did it three years ago when I was this little skinny girl the size of spaghetti, so I definitely can do it now.

"I still have a few years to physically mature but I'm definitely stronger than I was a year ago."
