Derby coach Andy Garner has set his sights high after another convincing home performance proved too much for Huddersfield who crashed to a 3-0 defeat at Pride Park.
First half goals from Craig Bryson and Jamie Ward put Derby in control and a Richard Keogh header just before the hour finished off Huddersfield who had skipper Peter Clarke taken to hospital for a precautionary scan after he suffered concussion.
Derby went out of the FA Cup at home to Blackburn last week and Garner said they had something to prove after that result.
"It was a disappointing performance last week so we wanted a response and we got one today," he said.
"We were outstanding from the first minute to the last and everybody was on top of their game out there. There's no reason why we can't make the top six. It's a very good squad in terms of effort and honesty and when we are on it, we are as good as anything in this division."
Huddersfield caretaker boss Mark Lillis had no complaints about the defeat to one of his former clubs.
"Derby played very well and all credit to Nigel (Clough), he's doing well and they looked like a top six team," he said.
"It's been a tough week for us and we caught them on a good day and they deserved the win. But there's no lack of application or commitment on the pitch and I am proud of the players."
But Lillis has no intention of putting his name forward for the vacant manager's job.
"My main focus is to take training on a daily basis and to keep everybody together.We are in the process of going through applications but the main thing for me is to pull everyone together. I am not going to throw my hat into the ring because I am the academy manager of Huddersfield and I'm honoured to be that."
