Maria Sharapova's lawyer on Monday blasted WADA chief Craig Reedie for making remarks about the five-time Grand Slam champion at a conference in London, and said the Russian tennis player is owed an apology.

The criticism came in a statement by Sharapova's management company, IMG, after Reedie commented at a World Anti-Doping Agency conference on Sharapova, who is serving a two-year ban after testing positive for the prohibited substance meldonium.

"For me the only satisfactory element in Madame Sharapova's case was that in one year she can earn more money than the whole of WADA's budget put together," Reedie said.
