The Brazilians open their Caf Champions League account against ES Setif on Saturday.
Sundowns have been drawn in Group B also alongside Enyimba and Zamalek.
“It is the group of death in my opinion. One wins or two wins…anything is possible,” said Mosimane.
The coach fancies Group A that has ASEC Mimosas, Wydad Casablanca, Zesco United and Al Ahly.
“You look at ASEC, not to say that I am thinking they are weak…you look at ASEC and our neighbours Zesco. Zesco we have played them four times and we always come up with good results.
“That space we know it and you’d think that we would do much better there. We now have one of ASEC’s best players in Bangaly Soumahoro and he told us we are stronger at this point in time so maybe the other group would have been better.
“But. it is important to find your level and to really, really test yourself with the best so just go for it, you can’t choose,” Mosimane told the media.
