"The football side of the club is 100% my responsibility," the Posh chief told the Peterborough Evening Telegraph. "Not the players', not the staff's, but mine and perhaps I have made a couple of mistakes by saying a bit too much publicly.
"I had a long, hard think after the game at Leicester on Tuesday. I've looked at myself as well and the way I have managed the expectations here.
"Maybe I shouldn't have said that the play-offs were the target. It is not that I don't believe we are capable of getting there, but I perhaps should have kept our aims for the season in-house.
"I could have put a bit too much pressure on the players by saying those things. If it comes down to my inexperience as a manager, I hold my hands up."
