Orlando Pirates starlet Siyabonga Ndlozi could make his competitive debut for the Soweto giants in the Caf Champions League match against Al Ahly on Saturday.
The PSL side have already secured their place in the tournament's quarter-finals after defeating CR Belouizdad at the Orlando Stadium on Sunday.
Although experienced players Thabiso Lebitso and Deano Van Rooyen are available for selection, Riveiro might field some of his fringe players, including Ndlozi.
With Thabiso Monyane having sustained a hamstring injury during the league match against Cape Town City last week, Ndlozi, who is a right-back and right-winger, could potentially make his debut for Pirates this weekend.
