"I was really pleased," said Johnson. "I'm well chuffed for such a young group. We've really grown up and the character we've shown is exceptional.
"James Bree, to come in having been injured and to go and play 120 minutes then score the winning penalty is fantastic. We gave a debut to Nick Townsend and Matt Templeton and we've come away winning the game against a very, very experienced and many-league-games-on-the-pitch Scunthorpe side.
"I think it could have been three-all. Marley's missed a penalty. Conor Hourihane's missed a chance. I thought our concentration levels were good today. I was delighted today, not just with the win, because if we'd not have won I'd still have the same thoughts.
"Putting Josh back in the middle, of course, made a big difference because of his energy and his quality. We had round pegs in round holes and that was important today.
"We've got another set of minutes in people and we're still catching up with a few such as Sam Winnall and Conor Hourihane.
"Nick's made some great saves. I was really pleased with him. He looked assured and solid but it's no fluke because he trains like that every day. He's took his chance and he's genuinely pushing Adam.
"I'm delighted for James Bree. He's young so he will have peaks and troughs in his form. He's a fantastic player and he's got a great future. His all-round game was excellent today. If anyone would have watched him today, they'd say he was a superstar in the making.
"I felt sick all weekend because it's like a cup final and it hurts. But we are young and today we got our game out. We popped it about nice and, at times, they couldn't live with us.
"I couldn't be prouder of my boys."
