Northampton Town manager Chris Wilder has criticised his underperforming players after four straight defeats.
The Cobblers lost 1-0 at Luton on Saturday and are 18th in League Two.
Wilder told BBC Radio Northampton: "[Assistant] Alan Knill has said to me we can't have too much of a go at them but I've taken no notice.
"It's a man's game. I went round the players [rating them] A, B or C. Over the last four or five games, there's a few Bs and the majority are Cs.
He continued: "There are hardly any As. On their day, they can produce A* performances, which we've seen already. But these are the times you get judged.
"At the minute, we're not very good and obviously myself and Alan are a part of that."
A draw with Wycombe preceded defeats by Burton, Cheltenham, Oxford and Luton and that run has resulted in Wilder's side slipping from fifth in the table.
An injury crisis has affected the squad, but Wilder says they cannot use that as an excuse.
"It isn't good enough, regardless of anything else," he said.
"We shouldn't be at all happy about the current position and situation. Players come into the team and I'd be a little bit embarrassed if people kept talking about the injuries.
"I think we've still got decent enough players out there to battle it out with at team at the top of the league.
"There's some big players unavailable and they're not going to be available for three or four weeks. We've got to go again and believe next Saturday is the one where we get out of this poor run."
