Egypt shocked Italy 1-0 as football's World Cup holders cracked under pressure in Johannesburg to leave their Confederations Cup fate in limbo.
Mohamed Homos was Egypt's hero with his 40th minute header enough to hand them a famous victory in front of 51,000 fans.
But the African champions also had goalkeeper Essam al-Hadary to thank for pulling off a string of fine saves.
Egypt and Italy are now level on three points in Group B with the Pharoahs favourites to go through to the semi-finals.
They face the United States on Monday while Italy must play Brazil, who have two wins out of two after beating the United States 3-0 at Pretoria.
