In the aftermath of Maria Sharapova's shock admission to failing a drugs test, a host of tennis' current stars are now opening up to give their take on the matter.
Serena Williams was the first, with Caroline Wozniacki following suit, but the most recent to share their opinion was 14-time Grand Slam winner, Rafa Nadal.
In typical fashion, the Spaniard didn't mince his words during a pre-tournament press conference ahead of the Indian Wells Open: "It's terrible news for our sport. It's terrible because our sport should look clean and be clean.

"The good news is we have a good anti-doping programme."
The topic of doping in tennis - and sport in general - has always been a delicate area of discussion. Suspicion and speculation has become part and parcel of drug abuse, but only until recently have confirmed cases come to light.
Nadal himself has been at the centre of doping allegations. Four years ago, former player Daniel Koellerer - who was banned for life following accusations of match fixing - questioned the Spaniard's return to top-level tennis after seven months out injured.
Former Belgian player Christophe Rochus made similar claims in 2014, accusing Nadal of taking performance enhancing drugs during the Australian Open.
When asked for his view on said accusations, the 29-year-old didn't hold back with his response.
He said: "No f***ing way, forget about it. I have never had the temptation of doing something wrong.
"I am very far from that, doping. I am a completely clean guy. I worked so hard during my career that when I get injured I never take nothing (banned) to be back quicker.
"I heard it a few times again about doping from my person and I am a little bit tired with that."
Talk then shifted to Nadal's current form ahead of the Indian Wells, the Spaniard confident his hard work will pay off.
"I'm practising hard and doing all the right things. I lost a couple of matches at the beginning of the season that I perhaps should have won.
"However, I feel much better prepared this year that last year."
