Petra Kvitova: "I think last couple of weeks show that I can play well on the clay. But this is a little bit different conditions here, as well. It can be hot as today. It can rain and be very cold. So the balls are not really flying as I wish. But that's how it is, and that's probably why it's the Grand Slam, right? So you have to be ready for two weeks of the best you can show. I think there is probably bigger favourites (at) Roland-Garros. And just for me to play my first match, we will see how it will go, but of course I will do my best, as always."
