Former WADA chief says Maria Sharapova only has herself to blame

Maria Sharapova has only herself to blame for failing a drugs test, according to former World Anti-Doping Agency chief Dick Pound as the Russian former Wimbledon champion faces an uncertain future in the sport and the cost of losing headline sponsors.

Sharapova revealed at a press conference in Los Angeles on Monday she had returned a positive test for meldonium, a substance she had been taking legally taken for 10 years to deal with health issues such as an irregular heartbeat and a history of diabetes in her family, but which was added to the WADA banned list at the start of 2016.
