Bemused Barry Ferguson reckons Aberdeen boss Barry Robson was just 'frustrated" when he claimed Connor Goldson should have seen red for a clash with Dante Polvara.
Referee Nick Walsh and the VAR team caught the ire of the Dons gaffer after the officials awarded a penalty against Stefan Gartenmann for a pull on Goldson's shirt in the closing stages of the Scottish Premiership clash at Pittodrie.
It allow Rangers captain James Tavernier to step up and level the game in injury-time and keep Philippe Clement's unbeaten record as Ibrox boss alive.
But that wasn't the only issue flagged up by Robson as he claimed that a collision between Goldson and Polvara on the edge of the area was missed by the VAR team - with whistler Walsh only opting to issue a yellow card for the flashpoint.
