A seething Wayne Bennett made his unhappiness clear after England laboured to a 38-12 victory over Scotland in the Four Nations on Saturday.
After suffering an agonising one-point defeat to New Zealand last weekend, England had been expected to bounce back with a facile triumph over the tournament's rank outsiders.
However, an abysmal start from Bennett's men enabled Scotland to take a shock 8-0 lead at Coventry's Ricoh Arena.
England eventually ran out comfortable winners - Elliott Whitehead's first-half brace added to by five home tries after the interval.
Yet a stony-faced Bennett was clearly far from satisfied as he bordered on the monosyllabic in a tense post-match news conference.
Invited to expand on the displeasure he had shown in a pitchside TV interview, the Australian replied: "Well, there wasn't much to enjoy about it."
He went on to accuse his players of taking Scotland lightly, adding: "They might have been reading the papers, I don't know. Reading about how they just had to turn up and win.
"I'm sure there was plenty of complacency - that's why we played like we did."
One journalist then asked England's coach to pinpoint what the team needed to improve on.
Bennett replied: "You name it, I'll agree with you.
"We weren't good. What we played last week to this week, there's no comparison."
England captain Sam Burgess insisted he still has faith in his side, who face a must-win clash against world champions Australia in London next Sunday.
"It's down to us now," said the South Sydney Rabbitohs forward.
"The bottom line is we got the job done in the end and the guys will come in ready to work hard next week. I certainly believe in my squad."
