"That could have been a potential banana skin tonight if we hadn't gone out and been professional," said Mackay, who rested all of the XI which started against City.
"We knew they were going to try and pack the area and make it difficult for us. We had to keep shifting the ball from side to side and eventually little gaps open up, which is what happened.
"As the second half wore on we were increasingly influential and looked as if we were going to score."
