From wiki:
Between 2001 and June 2006, Blanc was nominated CEO of the French Tennis Association and, as such, was the manager in charge of organizing the French Open (Roland-Garros), the Paris Master Series, and the Davis Cup/Fed Cup tennis events when staged in
France. During his tenure, the French Open reached a new level of development and success
thanks to Blanc's innovative ideas, like adding an extra weekend of Grand Slam tennis by starting the tournament on a Sunday instead of a Monday.
It's big brain time in Manchester.
