It's been more than a decade since the Serena-slam when a 20-year-old Serena Williams held all four Grand Slams at the same time. This feat has not been matches in the years since.
At Roland Garros 2012, Serena Williams suffered a loss to unknown player Virginie Razzano. The multiple Grand Slam winner was shocked and chose to train with Frenchman Patrick Mouratoglou who owns a tennis academy five miles away from the venue of the French Open.
Amidst rumours of a romance between the American and her French coach one thing can be confirmed is that Serena has seen a great change in her personal and professional life.
Losing only three of the 77 matches she has played since her loss at the French Open last year, the younger Williams' sister has won Wimbledon, the US Open, two Olympic gold medals-singles and women's doubles with sister Venus.
At the French Open this year, Serena Williams has been flawless executing her game plan in every match. She faced a stern test against Svetlana Kuznetsova but was able to come on top.
The World No1 won her second title at the French Open with a disciplined game execution against World No2 and defending champion Maria Sharapova.
The American has found a sweet spot in her game and will be hard to beat on her favourite surface as Wimbledon starts in two weeks.
At 31, Serena is playing some of her best tennis and as she said after her win at Roland Garros recently she is just peaking.
