Thwala, who is a Safta winning actor and has a resume envious of most actors - is apparently being headhunted by Uzalo.
He has appeared in shows such as Generations, Scandal!, Soul City and Isidingo. Thwala joined Isibaya three years ago and has since turned into one of the soapies lead actors.
According to Sunday Sun, Uzalo producers are keen on having him join their production and are even prepared to fork out any amount to secure him.
"Siyabonga is in a difficult situation. He's aware of this and is still weighing his options - as Isibaya treats him like a king," a source told the paper.
Another source said: "Siyabonga is doing very well in businesses and acting. He just bought a new BMW X5..if he migrates to Durban, that won't be an issue."
When contacted for comment, Mzansi Magic said they were unaware their top talent was being headhunted while Radebe said he had not heard from Uzalo.
