United found themselves 3-0 down at the 60-minute mark against Oxford last Saturday, but three quick goals gained the Iron a point.
Taking the positives from the remaining 30 minutes of that game, Perch also previewed the cup clash against Burton.
He told iFollow Iron: “In the end, it was a good point and we definitely felt joy rather than dejection. I was very impressed (with the side’s comeback) because it shows great character and determination.
“People probably thought we were dead and buried at 3-0, but we had belief and we managed to pull it off. There were still negatives from the game, but a lot of positives as well. It has given us a lift.”
Burton will make the visit to Scunthorpe on Saturday for the first round of the FA Cup and the 33-year-old wants to take the plus points from last week into the match.
“We need to start on the front foot and really get at the opposition because we have shown when we do that, we score goals at will,” said Perch. “We have to start like that, even if we go into it with the mindset that we are two or three nil down.”
However, the midfielder knows that the Brewers will make it as hard as possible for the Iron, following their previous meeting this season that ended 0-0.
Perch said: “It will be a tough game. When we played them earlier in the season, they were well organised.
“Nigel Clough (Burton's manager) will take it seriously with his affection for the FA Cup. It will be a proper FA Cup clash.”
Perch also spoke about the competition in general having a positive effect on a team’s league form.
“I think it is great and I love it," he said. “I have had good and bad experiences, so it is a bit hit and miss, but a good cup run can make your league form better as well.”
