The Magpies lost 1-0 to Barnet.
“It wasn’t tough, it was poor - simple as,” Nolan said.
“My players couldn’t pass a ball to each other and I told them afterwards that this is the first time I won’t protect them.
“That was not good enough for me. We improved for five to 10 minutes in the second half, but then they went back to doing whatever they wanted.
“That’s why they didn’t get the success they did. In the five minutes we asked them to do what we told them, they got a shot off and so on.
“I am not accepting it and they have got to book their ideas up and quickly otherwise we will have more afternoons like that.”
