To make matters worse, Nkosinathi Sibisi was sent off in the second half and will now miss the derby on Saturday afternoon.
“You right he’s not there, but there’s somebody who is going to be there," Riveiro told SuperSport after the game.
"We going to play with eleven, we have very good players ready to go so we going to miss Sibisi like everybody else but somebody will be ready to fill the space, we will be ready for Saturday."
The Spaniard was asked if he was still confident heading into the next batch of fixtures, which includes back-to-back games against Chiefs.

“If I’m confident, imagine if I say no. I have to be confident, I think these players, this team during the whole season give everybody results to be confident so it’s not the fact that we lost one game.
“Today, its not going to make us not feel proud of what we’re doing together or proud of this team and for sure on Saturday they will be back,” he added.
