Furious Derek McInnes believes that his side should have awarded a late penalty in the 1-0 defeat from Celtic.
Andrew Shinnie was involved in an incident with Jozo Simunovic late on as the Dons pushed for an equaliser.
It seemed that the Celtic defender tugged on Shinnie’s jersey before Erik Sviatchenko cleared the danger.
Celtic should have been three or four up long before the Shinnie incident with McInnes in no doubt that his team were denied the chance to snatch a late equaliser by referee Steven McLean.
“I feel as though we should have had a penalty kick with Shinnie,” the Aberdeen boss said. “He should be rewarded at least for his honesty by not going down.
“He’s been pulled by Simunovic and I think a forward player feels that contact and goes down but he should still be rewarded for his honesty, it’s still a pull on him and it’s still a penalty kick.
“And at that stage of the game I felt Celtic were really up against it.”
McInnes had no comment to make on the incident in which Johny Hayes was given a yellow card despite knocking Scott Brown to the ground.
Tom Rogic scored the only goal of the game in the 23rd minute to put Celtic 10 points ahead of Aberdeen with a game in hand at home to Partick Thistle.
It was the fifth successive domestic clean sheet for Craig Gordon who pulled off an incredible finger tip save from Sviatchenko in stoppage time.
