Former Bloemfontein Celtic head coach Letsoaka has been tipped to take over at Goble Park until the end of the season amid reports Giovanni Solinas is leaving the club for the second time.
According to a source close to Stars, Letsoaka's contract has been finalised and he will start drilling the team on Wednesday.
The ex-Golden Arrows boss will be aided by long-serving Stars official Sithole, who has been working with the MultiChoice Diski Challenge side alongside David Vilakazi.
"It's a done deal," says the source. "Serame is the new coach for Free State Stars and will be assisted by Themba Sithole."
