Motherwell dominated from the start on Sunday afternoon and cantered to a 5-1 victory, their sixth success in their last seven visits to the capital of the Highlands.
Michael Higdon and Jamie Murphy put the visitors in command and although Richie Foran's strike offered a flicker of hope for the home faithful, that was swiftly extinguished by further goals form Adam Cummins, Henrik Ojamaa and Omar Daley.
He said: "We never played from the first whistle to the last. We were comprehensively beaten.
"We just never got going today and that was disappointing, especially in front of a television audience.
"I didn't go mad at the players. In fact, I had a bit of a laugh and a joke with them.
"They are a great bunch of guys but today it was like a team of strangers turned up. We weren't at the races.
"I could still be in the dressing room on Tuesday going through every player's mistakes but there's no point dwelling on that.
"It's one of these games that we'll have a look at the DVD, although not a long one, then we'll throw it in the bin and move on from there.
"We are a positive club and we want to move forward together, which we'll do for the rest of the week and make sure we are ready for Celtic."
