Goodhue said: "We came back at them in the second-half and gave them a real scare. We really got on top of them when the rain was pouring and made life hard for them.
"If we can reproduce that kind of form in the Premiership, we will be causing teams problems."
Despite a daunting 21-point deficit at the break, Alex Grove and Mike Williams went over the whitewash to bring Warriors to within nine points of Sharks.
And according to Goodhue, the 16th-man influence seemed to work for the players as they constantly threatened the visitors.
He admitted: "Everyone was cheering us on in the rain and it helped us play some super rugby.
"But because of Sale's lead, we had to play mistake-free rugby if we were to make a comeback and win that game. Unfortunately it was a couple of basic errors which let them off the hook."
The New Zealander confirmed it was a challenge against a strong Sale side and if Warriors are to make strides in all competitions, they need to shut teams out early on.
He concluded: "It was tough out there. They dominated us in the first 40 minutes and once they managed to get some early points, it made it hard for us to come back.
"When they scored a try in the second-half, we were always going to be playing catch up but we showed today that we can be a dangerous side. We just have to cut out those errors."
