Riding French Open Champion, Maria Sharapova is clearly in the driver seat focused on defending her first ever Roland Garros crown. The world number two had always struggled on the claim until she found that footing a year ago and breezed to the title.

I do enjoy a little bit more now, just because I feel like I worked on that aspect of my game and I really improved and now I feel I don't have any excuses. When I get to the core and when I'm moving around, like just because I don't feel great one day, I can't, you know, I can't really won about it, because at the end of the day I didn't win the right topic. So I'm doing my myself at that time.

The French Open event kicked off a banning year that saw Sharapova briefly regained the world number one ranking, won a silver medal for Russia at the London Olympics and be named Forbes’ most successful female athlete.

I do make, you know, great money for a living and, you know, for the one who wanna play tennis again, have enough money to live through the rest of my life. But I do respect the money that I've made because I didn't grow up having a lot of money. It's so important to be able to look back at those days and think, you know, I really came from nothing. You know, we had a dream and I had a talent and we moved to the United States.

Her hard work paid off when she stunned the world and won Wimbledon in 2004. Grand Slam titles followed at the US Open in 2006 and Australian Open in 2008. But in 2012 Sharapova won the French Open and completed a career slam.

I don't know. But it's lucky or if it's just things following to play, so the four Grand Slams I won, or all four of them that were different. You know, who knows what the future will bring me and who knows what I may add to that list, but so far I can say that, yeah, I'm pretty fortunate to be one of the few that has achieved that.
