Calderwood rues defensive errors

Calderwood said his side defended poorly in the second half

Aberdeen manager Jimmy Calderwood said defensive mistakes cost his side dearly in the 3-1 defeat by Celtic.

"The first half we were dominant and had them on the back foot," he said.

"We knew Gordon would give them a rollicking at half-time and we warned the players. The second half we weren't as crisp in our passing.

"Defensively we were poor, which we weren't in the first half. I'm just annoyed that the game finished the way it did."
