Sundowns jetted out of the country on Wednesday ahead of their first round, first-leg tie with the Libyan team in Cairo, Egypt on Sunday.
The Brazilians are notably without star goalkeeper Denis Onyango and influential midfielder Themba Zwane among others through injury.
Mosimane said: "It's difficult, we can't get footage. Why we don't get footage is because a team has to be in a certain league so that we can upload footage. They must be on TV. They are not on TV, you can't see something.
"But we sent our analyst to help us there. We've got footage, a little bit. We have direction. We have a sense of direction of how they play, but you know how the North African teams play. The Libyan teams, the Egyptian teams, the Moroccan teams. Same culture of football, good technique. Organised teams, but rigid in structure.
"We have to dig deep. If we don't score, we don't concede. We can sort it out at home because our players give North African teams a tough time. The reason being we play different. They don't like people who dribble a little bit."
