Truro City boss Lee Hodges said his side showed Ebbsfleet United 'too much respect' after they lost 5-2 in the first round of the FA Trophy.
Liam Enver-Marum gave Ebbsfleet the lead after two minutes, but Les Afful equalised 16 minutes later.
Michael West and Nathaniel Pinney then struck before half-time and Enver-Marum completed his hat-trick in the second half before Afful got a consolation.
"We showed them too much respect in the first half," Hodges said.
"It was a case of us going out there and just watching them play instead of getting in their faces," he told BBC Radio Cornwall.
"I just think they might have been a little bit over-awed. I don't know why because there's enough players in here who have played as many league games as they've done."
And Hodges was angry that his side appeared to lack the necessary fighting spirit.
"We just seemed to let them dictate the game which is surprising really because you'd have thought we'd have been up for the fight, rolled our sleeves up and had a right go.
"They haven't had to work too hard for their goals, where we've had to work extremely hard to score anything and that's what disappointed me the most," he added.
