Pavel Pogrebnyak found the net for the first time since January as he netted a brace and, although Will Hughes gave Derby hope, substitute Nick Blackman inflicted defeat on the Rams, who have yet to record a home Sky Bet Championship victory this season.
Clough admitted: "It's a bit like deja vu at the moment. We are conceding poor goals, playing quite well but conceding poor goals. It's very, very simple, there's no complication to it.
"There was a 10 or 15-minute period after half-time when we didn't play well and we conceded two goals. We created situations throughout the game but unfortunately we got into great positions and didn't deliver.
"The first goal was very similar to the one we conceded against Leicester and we spent 15 minutes on Friday working on exactly that free-kick so it's a little but frustrating to say the least.
"I thought we played well but I said to the lads that all the hard work, all the positive elements of the performance get lost in the result. But I do think someone is going to get a hiding, I'm not sure when it will be but I think someone at Pride Park will cop for it, I just hope it's sooner rather than later."
