Former world No. 1 Caroline Wozniacki, who hasn’t won a tournament in nine months and lost in the third round of Roland Garros, says she can succeed at Wimbledon. Wozniacki recently hired 2002 Australian Open titlist Thomas Johansson to help coach her.

"I believe I can win Wimbledon this year, I have to believe," the world No. 7 told the Daily Mail. "The women’s game is wide open at the moment and the depth of quality players has increased significantly in the last 10 years. You never know what will happen, there will always be upsets and people you don’t expect in the quarters and the semis. I didn’t see Sara Errani getting to the final of the French Open but she had a really good tournament. I’ve brought Thomas in to help out and he has so much experience, is a Grand Slam winner and hopefully that can make a difference. My dad is still on court helping out and he gets along well with Thomas, but ultimately I’m in charge because I’m the one out there hitting the shots."
