First team coach Whittingham told The Argus: "It was a tremendous performance. The players deserve a lot of credit because they closed down and hassled Wolves and when they got the ball they played some good football too.
"I certainly think we deserved it. They didn't have a shot before they took the lead and you have to give credit for the players for the way they responded to falling behind.
"We expected Wolves to come at us in the second half but we defended superbly and still had chances to score ourselves on the break."
Crawley are 12th in the league table.
