Kevin Nolan cut a disappointed figure after Notts County's 1-0 defeat at Barnet.
Alex Nicholls' goal in the final minute of the game gave the Bees all three points on an inclement afternoon in the capital and the Notts manager was not happy with his team's showing.
"We were totally poor," he admitted. "We couldn't pass the ball to one another today. I told them that after the game and I cannot protect them because that performance is not good enough for me.
"We didn't work the goalkeeper well enough. They have got to buck their ideas up quickly or we will have more afternoons like that.
"The amount of pressure they put on us was minimal. They didn't allow us to play and fair play to Barnet. They are going to scrap because they're bottom of the league and they need to win games.
"When we have so many fans here sitting in those conditions, they deserve to have a go at us because the performance is not acceptable by the standards we have set ourselves."
The manager saw Mason Bennett pull up with a hamstring injury in the first half and faces an anxious wait to discover the extent of the problem ahead of Tuesday night's meeting with Carlisle United.
"I'm absolutely gutted because he has looked really good and sharp in training," said Nolan. "We're just hoping it's not going to be a long-term injury but we will know more in the next 48 hours.
"We're hoping Elliott Hewitt will be back soon. Jon Stead has been under the weather so we have tried to give him a bit of a rest and the likes of Lewis Alessandra and Alan Smith have missed out with illness too," he added.
