Clear communication with the players and not getting intimidated by aggressive appeals will be the key when the trio of female umpires -- Vrinda Rathi, Janani Narayan and Gayathri Venugopalan -- break new ground and officiate in the Ranji Trophy, a BCCI official said on Tuesday.

It will be a first for Indian cricket when female umpires will be asked to officiate in the men's cricket matches even as Gayathri has served as a reserve (fourth) umpire in Ranji Trophy in the past.
