"We have a couple of options but we'll see. His priority at the moment is SuperSport," said Binkin.
"We have been speaking with SuperSport for a number of months now so we'll see what happens.
"Many clubs are interested in him. There has been some interest overseas, so we'll see. At this point it would be a bit premature to discuss what will happen," said Binkin.
United could be tempted to cash in on their prized asset next month. Sundowns made a big push for the player from Matshelapata in Limpopo with a reported offer of R12m, which was rejected by United CEO Stan Matthews.
An insider close to the situation said an overseas move for Modiba is on the cards.
"SuperSport has made a contract offer, but Modiba is unlikely to sign it. If an overseas club offers to buy him in January then the club will sell him.
"I think if Sundowns also make a good offer in January then they will have to consider it, but remember, it will be up to the player ... he can still refuse," the source said.
Matthews could not be reached for comment as his cellphone rang unanswered.
