Aberdeen head coach Stephen Robinson told BBC Scotland: "We were too easy to play against and the goals we concede were too easy, which has been the story since before I came in here. That has to stop.
"We're in a relegation fight. If that wasn't clear before it certainly is after tonight. I've reiterated to the players that there's no hiding place now.
"People need to stand up. Aberdeen Football Club has been very good to this group of players but maybe home truths should have been told six months ago. They've been told now.
"I want a reaction soon and we need to have a reaction soon.
"I'm not angry, I'm disappointed. I see talent but people aren't putting their bodies on the line to stop goals and that's the biggest frustration.
"We have to do that. We have to work with what's here at the moment and we have to step up. We have to work on the training pitch and make sure that we make them better and give them that belief to do that.
"It's a bad run, and it was before I came in but you can't come to Ibrox and defend like that.
"I'm part of the group and I have to take responsibility but it has to improve."
