Coach Patrick Mouratoglou has been an inspiration to Serena Williams since 2012. Serena has won 8 majors in less than 4 years and may win USO this year. His former students include Grigor Dimitrov, Marcos Baghdatis, Laura Robson and etc. Does anyone know his tennis background? Was he a former ATP player? Is he like a Nick Bolleteiri type of coach (non former player coach)? I am sure Serena has helped his tennis academy business a lot in the past few years.
