Serena Williams better watch out that her boyfriend Patrick Mouratoglou isn’t getting her too cocky right before French Open 2015. Not only as the world number 1 revealed her relationship to her coach to the world, she also stated that different types of courts don’t phase her.

According to Tennis Magazine, the Serena Williams said that she is “indifferent” to different kinds of courts.

She said: "I'm not sure if this is a good thing or a bad thing, but I'm never really aware of the speed of the court," said Williams, who won Roland Garros in 2002 and 2013. "My friend Caroline [Wozniacki] always jokes with me, she's like, 'I never ask you whether the court is slow or fast.' Because I just don't know. I'm so happy just to be out there. For me it's all the same. Clay is slow, grass is fast and hard is medium, and that's just how I look at it."

Serena Williams and her boyfriend Patrick Mouratoglou have big plans for French Open 2015. Now that the world number 1 and her coach’s relationship is public, they can safely chart their successes together.

Serena Williams emerged victorious in Miami, but that doesn’t necessarily mean that the clay court season will come easily to her. She may need more coaching from her boyfriend Patrick Mouratoglou for French Open 2015.

Seeing how the world number 1 and her boyfriend slash coach have created this special partnership, it looks like Serena Williams won’t have to fumble through the clay court season, including French Open 2015!

The American tennis player said according to the Guardian, “I’m totally not as ready for the clay-court season as I thought I was. Now I’m in the mindset of, ‘You know what, I’m not on hard court.’ I’m playing like I’m on hard court and I’m not. So I have to play and be ready to hit a thousand shots if necessary.”

Serena Williams celebrated her Miami Open win with her boyfriend Patrick Mouratoglou. It looks like the world number 1 isn’t shy to hide her relationship with her coach.

There’s nothing better having your boyfriend as a lifelong coach!
