Rotherham manager Andy Scott saw his side go second in the table with a 3-1 win over Dagenham & Redbridge but kept his players in the dressing room for a dressing down afterwards.
Gareth Evans fired Rotherham into an eighth-minute lead, but they were pegged back when the visitors equalised with a 21st-minute header from Scott Doe. Two goals in nine minutes from Lewis Grabban got Rotherham back to winning ways after their first defeat of the season last weekend.
Scott, named this week as the League Two's manager of the month, said: "It was a 35-minute performance,. But it got us through. I thought that in that 35 minutes we were outstanding, but for the other 55 minutes we were poor."
He added: "And that is only because we didn't do in those 55 minutes what we did in the first 35. They have shown they are capable of doing what they did in that first 35 minutes, but for some reason after we scored the third goal we didn't do it.
"I have spoken to them for 10 minutes in the dressing room and told them it wasn't good enough and I'm not happy with it. We're joint top of the league, but standards have got to be better than that. If people want to play their own game I'm happy with that, but let them do it somewhere else."
Dagenham assistant manager Wayne Burnett admitted his side had not played well.
"We gave Rotherham too many chances," he said. "We didn't defend well, particularly for the third goal when we had a forward coming back to defend
"He should have got rid of it, but he played himself into trouble and we gave away a goal.
"For the first goal, maybe the goalkeeper could have done a lot better, but we didn't create enough ourselves, although we did hit the bar and their keeper made a couple of good saves.
"If one of those had gone it, it could easily have been different. I'm not making excuses, but we have a lot of players out injured and when we get them all back it will hopefully be a different story."
