Zungu's representative Steve Kapeluschnik yesterday announced his client would join Guimaraes in July, ending speculation over the Bafana Bafana international's future.
Kapeluschnik has since revealed the duration of the deal, which was penned amid widescale interest in Zungu.
"I can confirm that he has signed a two-year contract with Vitoria de Guimaraes FC," Kapeluschnik tells KickOff.com.
"There were offers from MSL, Italy, Germany and even locally but we opted for the deal with Guimaraes.
"He will continue playing for Mamelodi Sundowns until the end of the season," he adds.
