Jamie Ward punished a defensive mix-up to put Derby ahead in the 13th minute and although Chris Martin had a penalty saved by Ross Turnbull 10 minutes before the break, the home side increased their lead when Simon Dawkins scored five minutes into the second half.
Dickov said: "That's two weeks running that we've played ever so well. We came to a team whose form shows they are the best in the division at the minute and really took the game to them and caused them problems.
"Some of our football, especially in the second half, was top class. You talk about game defining moments and Theo (Robinson) was clean through and within seconds we are two nil down.
"There are lots of positives, they are one of the best passing teams in this division and we have more than matched them and out-passed them at times.
"The players showed a lot of quality on the ball and kept trying to do the right thing and I've got to be proud of them for that.
"But on the flip side we can't keep playing as well as we have done and defend the way we have for the goals. We are a young back four who are learning all the time and the goals we are conceding maybe shows that."
