Darren Ferguson said he felt Rovers had a demolition job in them before they thumped Southend United 4-1 to claim their first home league win of the season.
Ben Whiteman scored a ten minute hat trick early in the second half to help Rovers recover from going a goal down. John Marquis cancelled out Anthony Wordsworth's opener in first half stoppage time.
And Ferguson praised the resilience his side showed in recovering to run out comfortable winners.
"It's a good day and I think it has been coming," he said.
"We know we have got goals in us but we have to improve.
"And today there was improvement.
"The difference is we were clinical in the top end of the pitch.
"We'd worked on all week and spoken about all week about the improvement we needed to make in that area.
"And we showed it. We blew them away in ten minutes and the game was over.
"It ended up being a comfortable victory."
Ferguson was furious Wordsworth was not sent off for a kick on Jordan Houghton before he scored the opener for Southend.
But he said his players responded in the right way to things not going their way.
"Plenty of credit to my players for the character they showed, going 1-0 behind from a player that shouldn't be on the pitch.
"I said to them at half time everything seems to be going against us so this is a game we have to win to show that side of our character and the fact we really do believe in each other.
"The start of the second half we were so aggressive and go about them. The quality was superb."
"Copps' free kick was of real quality and Ben showed good composure to stick in in.
"And the third goal was outstanding.
"For the penalty, Alfie does what he does, getting down the side of people. Defenders don't want to defend out there and he gets past them to win it."
Ferguson admits he was baffled at the failure to send off Wordsworth for the first half incident.
Houghton fell on the ball as he attempted to shield it and Wordsworth kicked out after the whistle had gone.
He said: "It seems the fourth official made the decision and the reason they have given is he didn't think it was a violent kick.
"It's the most bizarre sort of reason I've ever heard.
"He's kicked him right up the backside.
"It's a clear red card.
"The decision wasn't given and he goes up and scores."
