Substitutes Sembegou and Ousmane Bangoura came on to score two goals that gave Guinea a 2-0 win over South Africa in their opening Group C match at the African Cup of Nations. Sembegou, introduced in the second-half, found the net with a diving header in the 76th minute from a low cross by substitute Ibrahima Bangoura.
Ousmane had barely been on the pitch for five minutes when his close range shot in the 82nd minute sealed the points for Guinea.
But the game could have gone either way, as the South Africans occasionally tested the Guinean side that failed to take an early lead.
Guinea's Fode Mansare was looking sharp on the left wing for the Guineans, with his series of runs giving several problems to the inept South African defence.
South Africa captain Sibusiso Zuma was unable to make a serious impression for his largely inexperienced side that had to cope with the more enterprising West Africans.
Guinea will be taking on Zambia in their second group game, which will be played on Thursday.
