John Coleman kept his players in the dressing room for a lengthy period of time after the 3-0 defeat to Tranmere.
"We were just trying to iron out things, there wasn't shouting and bawling," said the Reds boss.
"Defensively there is something wrong. We conceded another three soft goals - they will think they are good goals but on our part they are three mistakes.
"We have got good defenders but there is something not right, we are not defending properly."
He continued: "I have to look at myself. I have got to take responsiblity. We have trained really well over the last two weeks and maybe it's a hangover from not playing last week.
"Perhaps I can be guilty of being a bit cocky and getting a bit carried away and thinking we are better than we are and possibly not giving Tranmere the respect they deserve
"On the day they were ruthless in front of goal and we were wasteful."
