Gary McSheffrey was impressed with the way his side performed without the ball against Sky Bet Championship side Huddersfield Town.
Rovers were disciplined throughout and a second half penalty secured their fourth victory of pre-season so far.
He said: “We set up in a bit of a low block and sacrificed possession a little bit because we were coming up against team that came close to promotion to the Premier League.
“They didn’t break us down too often and I think there was only one or two saves for our goalkeeper, to limit a team like that was good for our belief and confidence.
“The challenge was to keep it like that for an hour, because we knew that was when their team would change and we would start to see more of the ball.
“The test then was to gain control, we’ve won it by George chasing a lost cause and earned a penalty which was tucked away nicely.”
McSheffrey is hoping his players take confidence from the way they went about their business at the Eco-Power Stadium.
He added: “We’re not embarrassed one bit by not having too much possession, because we knew after five minutes it was going to be a game like that.
“I’m delighted with our structure and keeping a clean sheet, we pressed high and forced them into a few errors by having a good shape.
“The performance has to give the lads some confidence, we won’t get carried away but we know if we can be hard to beat we’ve got players who can win us games.”
