The coach – who together with Craig Rosslee and Ian Gorowa is being tipped to succeed Roger Palmgren at AmaZulu – says he is humbled by reports linking him to Usuthu.
"To be honest with you I have not been approached by AmaZulu," Da Gama tells KickOff.com.
"It is always encouraging when your name is mentioned with a club such as AmaZulu because it shows that there are people who appreciate what you are doing in football," adds Da Gama.
"I am prepared to consider an offer that is reasonable but this can only happen if I am approached.
"There are two clubs that I have talked to but the offers they put in were not reasonable at all so I decided not to sign," Da Gama says.
Da Gama, who played for Moroka Swallows during his heyday, has also had coaching stints at Orlando Pirates, Bloemfontein Celtic and Free State Stars.
His is currently unattached since he left Platinum Stars before the end of last season.
