'Refereeing is the hardest job in the world'
Gbemisola Yusuf is a woman who likes to be in charge.
And, aged just 21, she is already refereeing football games in Nigeria, as well as for continental governing body the Confederation of African Football.
“Controlling 22 players on the field is amazing," she told BBC Sport Africa from the Maracana pitch in Ajegunle, Lagos.
This is no small feat, as Yusuf is amongst a relatively small group of female referees in her country.
