Derby assistant head coach Richie Barker admitted he still had frustrations despite his side’s 4-0 demolition of Northampton.
Barker thought the margin of victory should have been even bigger after Derby bounced back in style from defeat to Stevenage to blow Northampton away.
He said: “I’m pleased with the result but more so with the performance, the goals were excellent.
“My biggest frustration, if I’m being honest, is that it wasn’t more. It was a good opportunity for us to send out a real message but it’s about reaction and the ability to put things behind them 48 hours later and get on with it.
“Our reaction to losing the ball was excellent, we have to do the right things. People come here to watch goals, but you have to get the ball back to do that.
“Northampton ended up playing three different formations in the first half, which shows we created issues for them.
