The midfielder was shown a second yellow for a foul on Hlompho Kekane, allowing the Brazilians to go on and score an 81st-minute winner through Anthony Laffor.
“We came with a plan,” Mngqithi said after the game. “And we were looking good until the referee decided to go crazy. That craziness resulted in us losing.”
Sundowns coach Pitso Mosimane was understandably happy with the win that sees them into the quarterfinals.
“They gave us a hard time until they were reduced to 10 men,” Jingles said. “However, this is football … it happened to us against Swallows. “
He added: “Against Ajax we didn't play well but got the result, but it’s a cup game and today again we didn’t play that well but got the result. We needed this win to bounce back … I’m happy that we are winning.”
Mosimane also praised Laffor for his goal, saying: “It was an unbelievable goal. I spoke to my players before the game saying that we score difficult goals and miss easy chances. It needed guts and technique to score that goal and Laffor showed that he is an international player.”
