This was Guimaraes’ first win in five matches having undergone a decline in recent times. Prior to this match, Guimaraes had not registered a win in five matches.
Bafana Bafana midfielder Zungu saw the game out as Pedro Martins continues to prefer him over Ghanaian Bernard Mensah.
Zungu suffered a fractured shin in a match against Maritzburg United in February last year and went for almost a year without kicking the ball but South Africans would be pleased with the progress he is making.
The win sees Os Vimaranenses leapfrog Sporting Braga to fourth on the table while Moreirense’s relegation battle wasn’t aided by Friday's result.
Zungu and fellow African Ghislain Konan of Ivory Coast and Moussa Marega of Mali started for Guimareas while Mensah was brought on as a second half replacement.
Senegal attacker Pape Sougou started for the green and whites while another Ghanaian Emmannuel Okyere Boateng came off the bench.
