African Football Confederation (CAF) secretary-general Hicham El Amrani resigned on Sunday without giving an explanation. The 37-year-old Moroccan revealed his decision in a letter to African national football associations. His move is probably linked to the defeat of long-serving Cameroonian Issa Hayatou by Malagasy outsider Ahmad Ahmad in the CAF presidential election this month. El Amrani was a Hayatou loyalist, constantly defending his boss, who ruled African football for 29 years, against public and media criticism. He became secretary-general, initially on an interim basis, in 2010 when Egyptian Mustapha Fahmy moved to global football body FIFA. Ahmad, who will serve a four-year term, is scheduled to meet CAF staff on Monday at the Cairo headquarters of the 60-year-old organisation.
