The victory ended a run of five games without a win for Sundowns, putting a dent in their title charge.
A Clayton Daniels own-goal, to go with strikes from Themba Zwane, Mzi Mashaba and a brace from Khama Billiat, sent SuperSport spiralling to their worst defeat since a 5-0 loss to Arcadia in 1990.
“We broke the ice, when luck is with you … I’m not saying we were lucky to win, I’m talking about the first goal that deflects [in off Daniels],” Mosimane told SuperSport TV. “But in the first two or three minutes, Percy [Tau] got one-on-one with the goalkeeper and missed.
“I was saying, ‘Oh, is it our night again are we still in the same space.’ But luck came … but the rest of the goals were just the right decisions and applying the right technique in front of goal.
“But we have been playing like this, we just haven’t been scoring, when you break the ice it breaks in a big way. I’m happy for the boys.”
Mosimane feels the performance was not that different from the games that had seem them drop league points and bundled out of the Nedbank Cup by Lamontville Golden Arrows at the weekend.
“This is Sundowns, if they convert their chances … I can tell you it could have been like this with the last three or four opponents. For me it’s not about the derby, it about the three points, who you are playing against doesn’t matter.
“It’s unbelievable how football works … football is really amazing. You can play well and not win … but tonight we won. But this is Sundowns, when the ball goes for you we can beat anyone, it doesn’t matter who we play against.
“I’m happy for the fans, I’m happy for the boys. Me, I’m forever stressed because for the last four or five games … but they have found their confidence and the people [fans] have found their voices. We are the last ones to talk.”
The two sides met again in another league encounter at the same venue on Wednesday.
