Mosimane master-minded the downfall of his former club, as the Red Devils progressed to the semi-finals 3-1 on aggregate after a 1-1 draw in the second-leg at Lucas Moripe Stadium.
"I remember the first time I came here with Mamelodi Sundowns to play against SuperSport United, I was emotional little bit emotional because I spent seven years at SuperSport United but we're professionals and this is a game of football," Mosimane said in a press conference after the game.
"But I was little bit emotional only when I saw the placards outside and they stop the bus and all these people swearing at me, swearing at my mother.
"I said to myself, what else I should have done for this team to get the respect? But it's football I understand and I know the person who did that. And I know the person who is behind that.
"Just bitter because I left, I had to move on with my life, there's more, I don't want to talk, the things that I've received before my match from South Africa, if I show you my phone, correspondence I've received, emails I've received, they just don't let me go," he revealed.
