Sundowns, who are due to arrive back from Egypt today, now have a big mountain to climb when they host Al Ahly at home on Saturday, when they will have to beat the visitors by at least three goals.
Brazilians coach Pitso Mosimane has conceded that his team is now facing a mammoth task to overcome the 2-0 deficit suffered in Cairo but promised to turn up the volume at Lucas Moripe Stadium in the return leg.
"I think we played okay. We played well. Just that the two goals are bit difficult for us to turn the result around," said Mosimane.
"But we have to turn the volume up in Pretoria. We have to. We don't have any other option, we have to score in Pretoria.
"Congratulations to Al Ahly, they are good team, they are a big team. There was a lot of pressure but we managed to deal with the pressure."
