Caroline Wozniacki is confident that her new coaching relationship with former Australian Open champion Thomas Johansson will work out. Wozniacki and her father Piotr, who is also her coach, have decided to hire the Swede for the rest of the summer. Johansson, who like Wozniacki lives in Monaco, may come to Roland Garros in the next few days.

"I worked with him couple weeks before, and he's a great guy," she said. "We have a good connection. Also he lives just underneath me, which makes everything easy when you're going to go for practice and everything. He's played on the tour before. He's won a Grand Slam. He has the experience. He knows the women players because he's been commentating. I think he can come with some advice and some tactical things. He's a hard worker as well, and I think that really suits me."

The Wozniackis hired coach Ricardo Sanchez at the end of last year, but that relationship only lasted two months.

"It's definitely different, because during the whole of my career I've always had someone there as well who just comes with some inputs or a second voice that's helped my dad," she said. "My dad has been my main coach since I grew up. With Sanchez I wanted to do something that was a bit different and maybe try to give him more initiative. But this time I think already what I've worked on with Thomas, it's been working well. I mean, he tells me what he thinks and he's not soft, which I like. I don't like when someone tells me, 'Oh, it's great, it's great' when it's actually terrible. It's not terrible. It can't be terrible. But it's not good or I don't feel it's good. I want someone who is strict and tells me things how they are. He's like that. Also if something is good he tells you it's good  Just to have someone else there in the camp as well who can see a little bit different."
