Aces have tied up the two former Orlando Pirates defenders, who have formed the backbone of their team over the past two years.
According to Aces’ CEO Peter Koutroulis, Tlhomelang has agreed to a season’s extension while Musasa has added another two years to his deal.
“The two players are quality professionals and have the discipline we need in our mission of promotion next season.
“They have given good service in all the time that they have been with the club. Our intention is to hold onto the majority of our players and then just sign a few quality players next season because we want to continue with the squad we have.
“Next season we must go to the PSL to justify the support that we have from the local community here and the finances that have been ploughed into the club by the owners,” says Koutroulis.
Koutroulis adds that they are hoping to extend the contracts of a further five players by next week.
Aces have advanced to the semi-final of the Nedbank Cup after beating Nathi Lions 2-0 at home this weekend.
