Aberdeen manager Craig Brown has criticised his side's defence for their defeat to Inverness Caledonian Thistle at home on Tuesday.
The Dons went down 3-2 at the Pittodrie Stadium and missed the chance to move to the top of the Scottish Premier League.
"To lose three goals at home, when we've got the second-best defensive record in the league is unacceptable," he told the BBC. "I think, when you're a goal down and get back to 2-1 up at home, you shouldn't lose the game - and we contrived to lose it."
"The first one (goal that Aberdeen conceded), there were circumstances there that we don't agree with. I thought it was a free kick, it wasn't given and we lost a goal.
"For the second one, we softly conceded a corner unnecessarily and from that they headed the goal. And the marking at the corner was, again, poor. The third one we were defensively all at sea."
Aberdeen remain a point behind leaders Celtic in fourth place in the league standings.
