Leopards already lost Edgar Manaka to Platinum Stars in August, and now could find it hard to hang on to Ntshangase, who was one of their star performers last term.
According to a source close to the player, Bucs and Downs are keeping a close eye on Ntshangase.
"There is huge interest from both Pirates and Sundowns," says the source.
"Chippa United were the first to show interest but it's obvious they can't compete with both Pirates and Sundowns.
"There might be big move for him in January."
