Mabululu, in the 41st minute, scored the only goal of the match.
The Angolan team will play again next Sunday against the South African team, in the same city.
The two games serve as preparation for the 2023 African Cup of Nations (CHAN), a competition organized by the Confederation of African Football (CAF) and played between African teams formed only by players who play in the respective national championships. The competition is played every two years, alternating with the more famous African Cup of Nations (CAN).
