Derek McInnes has said that Aberdeen were "relentless" during their Scottish Premiership victory over Celtic.
Paul Quinn scored with four minutes remaining when he headed in from a free kick to give Aberdeen a 2-1 victory.
"From second one of the second half we were absolutely relentless in our determination to win the game. We made the game go our way and we got the penalty and should have had another one," McInnes told Sky Sports News.
"You talk about handball incidents and distance but this has came in about 20 or 30 yards and it has hit Charlie Mulgrew and he could have moved his hand to get out of the way of it so that should be a penalty kick.
"Then to have Jonny Hayes sent off was very harsh. I've looked at it again once and I know the speed of it and I know that is important with referees when they make decisions and he is going in at full pelt but when you actually see it he's touched the ball with his left foot and came in with his shin. It's actually a left winger's tackle."
The victory sees Aberdeen leapfrog Celtic into first in the Scottish Premiership table.
