In his post match interview with BBC Hereford and Worcester Graham Turner expressed his view that the players hadn't taken enough notice of all the pre-match warnings about Peterborough's front men.
"We got off to a bad start," said the Hereford United manager.
"For all the warnings, I'm sick and tired of telling them not to let anybody get in behind us. That was their big threat and within what three or four minutes they are in behind us for a goal.
"That is one thing I can not understand and can not except from players - when they are warned about the threat and we let it happen with one long straight ball that causes the problem.
"After that we looked lethargic, we're chasing the game, on edge.
"The young players who played so well on Tuesday suddenly found themselves chasing a goal.
"I thought to be fair to Peterborough they dominated the first half in the main but second half we gave it a go. We re-organised a little bit without creating too many chances.
"But the disappointment without a shadow of a doubt was the goal that we conceded. Had we come off with a goal-less goal we would have been quite happy.
"That was criminal, that's driven me mad that goal we conceded."
Next Saturday it's Leyton Orient and Turner admits his side will have to bounce back.
"We've put in good two performances and today we failed. We failed with any of our passing, we never really got hold of the ball."
