Hartlepool manager Mick Wadsworth urged his side to cut out the mistakes after they crashed 4-0 to leaders Charlton on Saturday.
Bradley Wright-Phillips scored twice in the first half at Victoria Park to give Charlton the advantage and the League One leaders never looked back as further goals were added by Danny Hollands and substitute Scott Wagstaff.
"At the moment we cave in to concede silly goals," said Wadsworth. "Even in winning at Chesterfield we conceded two stupid goals.
"We have six or seven players below their optimum level and we cannot do that.
"We plan each day in training, it's not willy nilly, but we have too many falling way short. I won't name names, we have to stick together and I need them like they need me.
"In everything I have done in my life, all the people I've met and the tough times, the one thing that sees you through is strength of character and personality - talent is second to those."
