Wetherby Athletic boss Mark Forster blasted his side’s potency after they failed to break down struggling Kippax.
Eleventh-placed Athletic were held to a goalless draw at the Ings on Saturday despite controlling the match.
And Forster said the match had made him the angriest he has been for a long time.
“It was the most one sided nil-nil you have ever seen,” he said.
“I was absolutely furious. It was the biggest dressing down I have given in my life.”
Athletic struck the woodwork twice but Forster criticised his frontline for failing to create incisive chances.
“It was like attack versus defence in training but we just couldn’t score,” he added. “It was two points just thrown away.”
Athletic welcome rivals Bardsey to the Ings on Saturday (kick-off 2.30pm).
The unbeaten reigning champions have been imperious so far but Forster said all his players were looking forward to the derby bash.
“It will be a very difficult game,” he said.
“I’m hoping for a good reaction. It’s a chance to test ourselves against the best team.”
