What other players are saying about Maria Sharapova's positive drug test for meldonium

The tennis world has been reacting to the news that Maria Sharapova has failed a drug test.

She's received a mixture of support and criticism and that's just from players - never mind her sponsorship deals.

Andy Murray said she "must accept responsibility" while Serena Williams said the 28-year-old showed "a lot of courage".

The Russian player tested positive for meldonium, a substance she's been taking since 2006 for health issues.

What Andy Murray said

"Clearly if you are taking performance-enhancing drugs and you fail a drugs test, you have to get suspended," the world number two believes.

Speaking to BBC 5 live he said: "I think, since 1 January, there have been 55 different athletes who have failed tests for meldonium.

"I find it strange that there's a prescription drug used for heart conditions and so many athletes competing at the top level of their sport would have that condition. That sounds a bit off to me."

What Serena Williams said

The world number one said: "Most people were surprised and shocked but happy that she was upfront and very honest.

"It's just taking responsibility, which she admitted she was ready to do."

What Rafael Nadal said

"I believe in the sport and the values of the sport," the 14-time Grand Slam champion said.

There has been speculation he has used performance-enhancing drugs in the past which he is "a little bit tired" of hearing.

"I have never had the temptation of doing something wrong," he said.

What Novak Djokovic said

"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," the world number one said.

What Kim Clijsters said

The former world number one from Belgium posted her feelings online.

She tweeted: Very disappointed waking up to hear the news about @MariaSharapova

What Maria Sharapova said

Since announcing she failed a drug test at the Australian Open, Maria Sharapova has kept a low profile.

But she did post about her fans on Facebook.
