Chiefs PRO Clifford Mogomotsi confirmed the ex-SuperSport United and Platinum Stars man is in their sights.
"We have a couple of players we are looking to sign. Zongo might be one of them," Mogomotsi tells KickOff.com.
"I will only be in a good position to talk about players we are signing after a board meeting this week."
Zongo was released from police custody in the Western Cape late last year after being arrested in connection with a rape case. It is understood the allegations date back to February 2013 when the 27-year-old was on the books of Chippa.
Zongo, whose career has been dogged by off-field issues, last featured for Royal Eagles in the National First Division in 2016.
