Charlie Palmer accused his Belper Town players of taking victory over Goole for granted after watching his side blow a two goal lead.
The Nailers raced into a two goal lead before Goole came roaring back to go 3-2 up.
Alex Steadman then dragged the game level from the spot on the stroke of half-time.
Palmer said: “The 10/15 minute spell where we conceded the three goals was extremely poor, I had to spell it out to the lads that we all make mistakes, but players who want to go on and play at a higher level, cannot keep making these same mistakes.
“I just want my players who are a good, honest group to learn from what they saw today.”
“When we went 2-0 up, not just young players, some experienced and older players thought it was going to be an easy afternoon and took the opposition for granted.
“We made silly areas and gave a poor side a boost of confidence, certain players took their foot off of the pedal.”
It was a game which saw Palmer’s son Gerome came off the bench to make his Belper Town debut.
“People will think I signed him because he is my son and he was playing at Long Eaton, their two forwards had good movement and it suited Gerome better than Ross (Parker) that is why I made the change at half-time,” he said.
“I am here to get results, I pick a squad of players that I think will do the best for this football club whether they are my son, cousin or friend. I am Belper’s manager and if I believe he is good enough he will be given his chance.”
Belper Town’s front three all scored again as the club continues to find goals easy to come by.
Added Palmer: “Stevo (Rob Stevenson) has got a spring in his step he is enjoying his football, Steady (Alex Steadman) will always score you goals and Evan (Garnett) has improved.
“What people do not see is how much Evan listens and how much he wants to improve his own game, I keep telling him to watch Jamie Vardy and watch he does not give defenders a minute on the ball. It was pleasing to see him take that on board and get himself a goal.”
