Serena Williams will compete in her first Grand Slam in 16 months as she returns to the French Open.
The American spent time away from tennis following the birth of her child and she is controversially unseeded.
World No 1 Simona Halep is the favourite to claim the trophy but she has never previously won a major tournament – losing in two finals over the last year.
Caroline Wozniacki, Garbine Muguruza, Elina Svitolina and Jelena Ostapenko are also in with a shot of success.
And Wozniacki is delighted to have Williams back on tour.
“I think it’s always great to have the best players play, and it raises your level,” said the Dane.
“You have to play your best level, and I think having someone like Serena back.
“It’s keeping us all on our toes and we have to keep improving all the time.”
