Pirates have all ready made contact with the 26-year-old, who is rated highly by new Bucs coach Muhsin Ertugral.
According to a source close to Mokeke, the ex-Ajax Cape Town man's future lies in the hands of Matsatsantsa mentor Stuart Baxter.
"There is no secret that both Wits and Pirates want him," says the source.
"Remember he is the only left-footed midfielder at SuperSport and is versatile. The club needs balance.
"The coach Stuart Baxter will make the final call whether SuperSport United keep or release him."
