The trio all were heavily involved in Sunderland's crucial 1-0 win and Hutchison believes that Newcastle were intimidated by the attacking threat his old side posed.
"They carried a real threat with that three-man forward line of Jermain Defoe, Steven Fletcher and Connor Wickham," he said. "Suddenly Sunderland seemed to be playing to their strengths – three strikers who have scored a few goals supporting each other. It scared the life out of Newcastle."
Sunderland have struggled in forward situations this season, but Advocaat's desire to play all of their more notable attacking stars has gone down well at the Stadium of Light.
Although there are still things that need to be worked on, the win over Newcastle provides them with a platform to build upon for the future.
The mood has been lifted around the Stadium of Light and there is increasing optimism that they will be able to avoid the drop, even after what has been a disappointing season.
Sunderland are currently three points clear of the relegation zone and will be determined to protect their advantage, with only seven games remaining this term.
