Liam Buckley admits he was left "fuming" at his St Patrick's Athletic players over their display in the home loss to an under-strength Bohemians.
A four-game unbeaten run was ended as a strong Saints side threw away a 1-0 lead to lose 3-1, to Buckley's disgust.
"As a footballer you have to come out, you have to make sure you give 100 per cent in trying to win matches. You can have a career out of doing that, but if you don't do that you end up with that sort of performance," the Saints boss said.
"We lacked drive, organisation, everything. That was as poor as it's been from us this season. Up in Sligo it was an eight out of ten, against Bohs it was three out of ten.
"It's difficult to put your finger on it, but I am absolutely fuming. That was, by a mile, the worst we have played this season. It was a lack of energy, a nothing performance, I am fuming with that.
"In fairness to Bohs, they have played well with their squad players. They jump above us in the league and now we are sixth, and we wanted to push on.
"It was an opportunity to get a few points and we throw out that performance, it's a sickener.
"The players are all capable of being organised on the pitch, having drive and energy, being disciplined. We do have a style of playing, but you wouldn't have guessed that."
