But Derry was not pleased with his players in the opening exchanges and said: "It was a disastrous start and I was really disappointed.
"We have a game-plan and that game-plan has to start in that first five or 10 minutes. We didn't carry that out and it gutted me.
"For the last two or three months we have wanted things to happen but they haven't fallen into place.
"(In this game) it went really well and I'm pleased for the players."
Liverpool loanee Coady had taken less than two minutes to break the deadlock for Clough's side, rifling home from the edge of the box following a neat one-two with Chris Porter and he almost doubled the lead three minutes later but side-footed wide.
County found their feet though and were level after 26 minutes. The dangerous Jamal Campbell-Ryce fizzed a cross into the box which hit Showunmi on the chest and bounced in.
Showunmi was almost the villain soon after, but Sheffield United appeals for hand-ball by the striker in the County box fell on deaf ears.
