Chelsea director Marina Granovskaia is expected to speak for the first time publicly next month.
The Daily Mail says Granovskaia arguably the most powerful woman in English football as the club's transfer and contract negotiator. She is also Roman Abramovich's day-to-day link with his football team.
She is confirmed to speak - at least according to the organisers - for the first time publicly to an audience of 300 senior sports industry figures at a women in sport conference planned by the Leaders brand on May 21.
Granovskaia, who sold David Luiz for a remarkable £50million, is understood to regard the occasion as an appropriate platform to reveal more about her work in sport, although Chelsea said last night that her appearance is "still under discussion".
