The Brazilians lost 2-0 in the away leg to Ghanaian opponents Medeama SC, bowing out of the competition on away goals following their 3-3 aggregate scoreline.
Yet Mosimane feels his side were hard-done by, venting his fury at the Algerian match officials in charge.
“In CAF, for South African teams, it’s very difficult … those guys were cheating!” the Downs coach told SuperSport. “Everyone says it’s difficult for South African teams who don’t want to play football, but the referees were cheating – you saw that. How can we play? I mean really …
“I thought what happened to us in South Africa against AS Vita was bad, but this was unbelievable! We had people from Medeama coming to our bench and fighting us, and we had to fight back! It’s unbelievable. It’s a jungle.
“The new Fifa president has a lot of work to do in CAF. Africa is behind.”
Mosimane was quick to defend his club against criticism that South African teams are unable to succeed in continental competition, believing unfair officiating is what ultimately cost the PSL champions.
“I’ll give my report to the club, and my team will decide what they want to do with these kind of games,” he continued. “It’s very difficult for South African teams – everyone accuses us of being soft and complaining about the pitch or travelling … no, we’re not complaining about any pitch or anything – it’s not in our hands.
“It’s terrible – two artificial set-pieces, the penalty and other free-kick … they had a chance to score in open play, but they couldn’t. These Algerian referees are unbelievable – and these are Fifa referees wearing the ‘fair play’ badge [on their sleeve]!
“What can we do as Sundowns?”
Sundowns will have another shot at continental competition next year, having qualified for the CAF Champions League by virtue of winning this season’s PSL title.
