ANGOLAN Football Association chairman Armando Machado has told a Luanda magazine that he wants to challenge Issa Hayatou of Cameroon for the African Football Confederation (CAF) presidency. Former international athlete Hayatou has ruled African football since 1988 and will be bidding for a fourth four-year term during a CAF meeting in Accra before the African Nations Cup kicks off on January 22. Machado, who has still to lodge a formal challenge, said he expects support from Portuguese-speaking countries and other states in Southern Africa. Egyptian Samir Zaher, who indicated last year that he will oppose Hayatou, is unlikely to contest the elections after resigning as head of the national association following a humiliating exit from the Confederations Cup.
