Aberdeen manager Derek McInnes accused his players of being too "indulgent" as they slumped to a 1-0 defeat away to St Johnstone.
Andrew Considine headed off the bar in the first half, but St Johnstone were worthy of a win which came through a late goal from Steven MacLean.
"I thought we were quite indulgent with our play at times," McInnes told BBC Radio Scotland. "We needed to cause them more problems.
"It's a poor afternoon's work from us."
Aberdeen should have found themselves behind early one when two mistakes from their defence gifted chances to the hosts.
MacLean hit the posts after Jonny Hayes' poor pass-back and team-mate Gary MacDonald blasted wide after Jamie Langfield had spilled a free-kick.
"That should have been the wake-up call to start imposing ourselves on the game," admitted McInnes.
"At half-time we said we needed to see more impetus, we needed to ask more questions, we needed to start working the goalkeeper that bit more.
"At the very least we should be bemoaning the fact it's 0-0 and coming away with a point when we've not been at our best, but we lose a goal and then we're chasing it from there on in.
"We got ourselves into some decent areas but were not convincing in the final third."
The Dons were backed by a travelling support of just under 3,000, and the manager was unhappy at sending them home disappointed.
"We know who we're playing for," he said. "You want to send them home happy.
"We've had a very good away record last season, we intend to have that again this season. We got off to a good start winning away from home at Kilmarnock.
"We knew they would come in big numbers here. To send them home disappointed like that doesn't sit well with any of us because we know who we're representing.
"We want to make sure they're proud of their team and pleased with what they see, and I think we'd all agree that wasn't good enough from us today."
Peter Pawlett was booked for diving, having earlier in the game been warned for the same offence by referee Craig Thomson.
And McInnes said: "I haven't seen either incident. I'm about 90 yards away from it.
"When he goes at that speed the slightest touch can bring him down.
"Once I have seen it again I'll comment and take action if I need to on the back of that."
