Russian tennis beauty Maria Sharapova has said that she was in the company of people who had achieved more than her when she enrolled for a global management and leadership course at the prestigious Harvard Business School.

It was during her 15-month doping ban after testing positive for meldonium, which was added to the list of banned substances at the start of 2016, that she decided to register for a two-week course that could help her expand her candy business Sugarpova.
