This comes after SuperSport United coach Eric Tinkler did not dismiss the possibility of selling the New Zealand international.
Pirates are also said to be interested in Brockie, but Sundowns are believed to be favourites to win his signature.
“We’ve heard that Sundowns have had an interest in Brockie for the last six months but as yet we have not received any offer,” Tinkler told the media.
“No player is not for sale. Every player has a price. You are not going to get me giving players for free, that’s for sure.”
If the deal does go through, the transfer of Brockie would be a landmark deal that would likely make him the most expensive PSL footballer in history.
“In the event he leaves then obviously we have to go into the market. If we lose one then we need to replace him, it’s as simple as that. At the moment, no one is leaving, which is why we have not been busy in the transfer window,” concluded Tinkler
