Darren Ferguson admitted he was frustrated by Doncaster's performance, despite their 2-0 win over Newport.
Goals from James Coppinger and Andy Williams helped Rovers to a fifth win from six league matches and took them second in League Two.
While delighted with the result, boss Ferguson says he demands more from his side.
"The players know we as a staff believe we set certain standards," he said. "We didn't get to anywhere near the level we can. It was a frustrating afternoon.
"We never really got going, we never really had any fluency to the performance. We didn't do the basics well enough. When we kept it simple and played one and two-touch stuff we were good, but we didn't do enough.
"I was never really comfortable. Even at 2-0 I never felt comfortable.
"But we saw it out. I'm delighted with the win and another three points going into three really tough games against Luton, Carlisle and Portsmouth."
All eyes were on Coppinger, playing at home for the first time since making his 500th appearance for the club, and he obliged by curling home a sublime free-kick after 17 minutes.
"I think James was glad when the game was over," Ferguson said. "He doesn't like all the attention.
"It was a big day for him.
"That is four goals and three assists in eight games, so he is producing at the top end of the pitch which is the most important bit."
Andy Williams made sure of the points with a fine finish after 59 minutes.
Newport manager Warren Feeney was angered by the awarding of the free-kick from which Coppinger scored and he also felt his side should have been given a penalty.
"It's been the story of our season, these decisions," Feeney said. "Sean Rigg was pulled in the box, I could see it.
"With the free-kick, Coppinger's run 10 yards with it and been tackled and the referee has called it back. Is that an advantage?
"There was one in the second half for us that was exactly the same and he played on.
"These big decisions cost us. It gave them the lead and the momentum."
Feeney was pleased with his side's performance overall but believed they gave away the goals they conceded.
He said: "I think the second goal just typifies us again, a simple mistake.
"I don't think we played badly. We created enough chances.
"There will not be many teams go to Doncaster and have a go like we did. We probably had the two best chances of the game in the first half.
"But we can't keep giving teams goals.
"On that performance I don't think we were too bad. We just can't keep giving teams starts."
