The third of the night was Carroll's first goal of the season and the boss admitted he was pleased to see his No.9 break his duck.
"Yes I'm pleased for him," he said. "And I'm pleased for Maxi who also got on the scoresheet for the first time this season. Obviously Luis is hogging the limelight a wee bit by scoring again but it's great, especially for Andy to get off the mark with fantastic strike.
"We are delighted for him. He might have come on a bit later had Raul not got injured. But he did well when he came on."
