Johnson was delighted to have secured such an emphatic win over Swindon and was delighted after a hard week of training.
"I'm really really chuffed," he said. "Chuffed for the players to be honest, they have put in so much work this week and training has been intense. They came to the front and delivered."
The Reds went a goal down early on because of a mix up in defence which resulted in Lewin Nyatanga scoring an own goal. Johnson thought the Reds did brilliantly to bounce back so quickly and equalise.
"The goal we conceded was sloppy communication wise which is what we had worked on all week, but then we came good. I thought Marley Watkins took the goal superbly. It was a big decision not to start Sam Winnall, but it worked."
Johnson added, "I thought Conor Hourihane was massive in what we did today, he was a captain out there. He recognised everything that needed to be recognised and helped apply pressure on them, meaning we started to nick things."
Reece Wabara produced a stunning strike before Half Time to send the Reds in with the lead, and Johnson said it's nothing unusual to see the players trying that. "We've been trying to get them all to shoot from range as they all have great technique. If you don't shoot you don't score, and I felt we could of had seven today!"
Johnson made a number of changes from last weekend's defeat to Shrewsbury and he felt his decisions were justified.
"We picked a team we thought was going to win today, and they did. We had everything. When we had a bad spell, then we came good again. If we keep doing everything eventually we are working on we have got the quality to break teams down."
After such a convincing win against a Swindon side that are considered to be one of the strongest in the league, Johnson sent a message to his players by saying this needs to be a platform to build on.
"It has to be a platform. I've always believed in the players qualities because i see it every day. What the platform has to be is the communication. When that slips we can look poor, when that's strong we look very very good. The league is so tight, we just have to keep in there. We will only get better."
