With the French Open just weeks away, the transition to clay has never been more important for the stars of the WTA. What is the most important aspect of the transition to them? Find out now - here are their thoughts...

Nadia Petrova: "Tactically, it's a completely different game. Clay absorbs power and slows down the game, so you can't go for the winner right away. You have to be more creative - you need to move your opponent around before you finish off the point. Also, the footwork is obviously different - you have to know how to slide. I've always enjoyed playing on clay throughout my career."

Shahar Peer: "The main thing is you have to be ready for long points and hitting a lot of balls. You still have to go for your shots, but you have to wait for the right chance. I had a very good clay court season last year so I'm hoping for another good one this year - I'm working very hard and hoping for the best!"

Jelena Jankovic: "For me, the most important thing is movement - like getting used to the sliding. Being fit and patiently constructing the points is important too, of course. I love playing on clay and am looking forward to this season."

Alisa Kleybanova: "My game is fast and aggressive, so I usually go for my shots a lot, but clay is different. It's nearly impossible to play just two or three shots in a clay court rally. You have to build the points more and play with more variation in your game, so that's what I try to do on this surface. You can't have the hardcourt game in your head because you'll rush things too much."

Samantha Stosur: "There are very few clay court specialists now, so there aren't too many adjustments, but I would say the two most important ones are your serve and patience. I try to use my kick serve more because it's not only high percentage, but you don't get rewarded for a big flat serve like you do on other surfaces. Also, being patient and working your points is imporant."

Caroline Wozniacki: "To me, the two most important things are making sure you have a higher margin over the net, and the movement - sliding of course."

Marion Bartoli: "You need to hit higher over the net. Also, one of the biggest adjustments for me is my positioning. I like to stand closer to the baseline on other surfaces but it's hard to do that on clay because players like to use the angles more on this surface. It's a completely different game."
