Notts County assistant manager Mark Crossley demanded more from the players following a 3-2 defeat at Barnet.
Goals from Michael O'Connor and Jonathan Forte were not enough for the Magpies as Bira Dembele's goal and Luke Gambin's brace secured all three points for the Bees.
And the 47-year-old pulled no punches in his assessment of County's current form.
"In the first half we were pleased with how we played but in the second half we could not deal with them," he said.
"We are on a bad run and the performances of late have not been good enough - that is the be all and end all of it. We take responsibility for that.
"The players have to stand up and be counted and show us what they are made of. We need more from them on the pitch.
"The amount of fans that we bring to these long away trips is phenomenal and I can only credit them.
"John and I fully understand their frustration and all I can say is that we will keep trying our best."
