No team have scored more last-minute Premier League winners than Wolves' three this season while Monday's equaliser was their fifth goal in stoppage time; which also joint leads the top flight.
Moutinho believes this is down to their never-say-die character and ability to remain clear-headed when the going gets tough.
"Until the referee whistles to the final of the match we never give up," Moutinho said before the Newcastle fixture. "We try to score one more to win the game - that's what we do.
"We need to be calm, focused, do it well, because if you are stressed, or nervous, maybe it is not possible to do the things you need to do very well."
Newcastle, meanwhile, have now conceded 12 goals in the final 15 minutes this season, which is the fourth highest figure in the PL. Their total one behind West Ham United in third.
