Yanga-Mbiwa is aware all eyes are on the players and how they react after being torn apart at the Etihad on Monday night.
"It was difficult to lose and even more difficult to lose like that," he said.
"A 4-0 defeat does not look good on us. It was bad for the players and for the fans. But we must not let this result ruin our season.
"We have two home games coming up and it's up to us to work hard and move on from what happened."
