Rangers boss Mark Warburton says referee John Beaton cost his side a point after awarding the free-kick which led to Aberdeen’s dramatic Pittodrie winner.
James Tavernier was harshly penalised for a foul on Johnny Hayes and the match official’s mistake proved decisive as James Maddison whipped home a stunning stoppage-time set-piece to seal a 2-1 victory.
It is another dose of disappointment for Gers, who have managed just two wins from their seven Ladbrokes Premiership fixtures, leaving them floundering in the bottom half of the table.
Warburton tried to play it diplomatically after the match but could not hide his annoyance at Beaton’s big call.
He said: “I thought the referee handled a difficult game very well. He did a really good job up to that point, but to give that one there is frustrating beyond belief.
“I will be careful what I say about the free-kick. Everyone saw the ball move. The fourth official on the sidelines saw the ball move and made a comment. And yet a free-kick is given.
“You have got to be, I think, 100 per cent sure in these type of games, in those areas of the park.
“It was an outstanding tackle. Late in the game, when your players are fatigued, I thought Tav made an excellent tackle there.
“I don’t think their player moaned about it and it is a huge decision to give and it cost us the game, but what can you do?”
