"Whether she competes or not should be decided by the end of the first week of Roland Garros."

World number one Novak Djokovic has given his support to Maria Sharapova and said he hopes she "gets out of this stronger".
Women's tennis' most bankable star made the stunning announcement on Monday that she had failed a drug test for meldonium at the Australian Open.
Djokovic and Sharapova share a racquet sponsor and Djokovic has famously done impressions of the Russian on court.
He told TMZ.com: "I obviously wish her all the best. I've known her for a long time. I feel for her with all that's happening and I just hope she gets out of this stronger."
Maria Sharapova has "no excuse" for not realising that the medication she was taking had a banned ingredient in it, Dick Pound has said.
Speaking to ITV News, the former head of the World Anti Doping Agency said; "There's no excuse for somebody with her experience for testing positive for something she knew about and had been warned about.
She was either recklessly indifferent to what messages she was getting from Wada and the ATP or she did it deliberately and thought 'maybe I'll get away with it'".
The Russian government has said that Maria Sharapova's failed drugs test should not be "projected onto" the whole of Russian sport.
Kremlin spokesman Dmitry Peskov also told journalists that Russia was against attempts to politicise sporting matters.
