The flying full-back was not at his best against the Tricolours as Masandawana recorded their first defeat of the season in the Champions League.
Mudau will be relishing another battle against To Carneiro who tormented him whenever the Angolan attack-minded full-back pushed forward.

The left-back was undoubtedly Sundowns' best player against the Tricolours and he grabbed the visitors' important away goal from a set-piece.
Lakay's delivery from set-pieces could be key to the Tshwane giants' win over the 15-time Angolan champions.

The gifted centre-back is most likely to be recalled to the starting line-up ahead of an out-of-form Mosa Lebusa.
Lebusa looked shaky against Petro with Tiago Azulao unsettling the former Ajax Cape Town captain and the Brazilian striker netted the opening goal.
