Reports suggest that Mudau has been keen on leaving Masandawana, but the club has not accepted offers for the right-back.
According to FARPost, the player is also said to be demanding an improved deal after Sundowns activated the one-year extension to his contract, which had run out at the end of June.
Sundowns and Mudau are said to be still in discussion amid indications that the two parties are set to reach an agreement, especially after the defender resumed training.
