Pitso Mosimane has earmarked Brockie as a perfect replacement for Khama Billiat should the Zimbabwean leave the club.
SuperSport CEO Stan Matthews, however, says the New Zealand striker is not for sale and the club wants to give him a new deal.
Brockie still has two years left on his current deal with Matsatsantsa.
“It is not really me who will have to give in if Sundowns keeps on pushing for a transfer‚ it is between SuperSport and Sundowns‚” he said on Thursday.
“I have spoken to Stan Matthews and he has made it pretty firm that they are not going to sell me because I am an important part of the club.
“I am an ambitious player‚ I like challenges and that is the reason I came to South Africa.
“To be honest‚ I can’t say too much more than that because I am under contract with SuperSport and it still has two years left.
“That’s where it stands at the moment.
“SuperSport are saying that they want to give me a new deal‚ so we will see how that develops.”
