Celtic’s Unique Angle footage captured frustration among Kilmarnock’s players immediately after Liam Scales scored Sunday’s winner.

While the Celtic defender celebrated his improvised finish, the visitors were left examining how he had found space inside their penalty area.

George Stanger made his complaints clear after the ball managed to make its way back into the box after the visitors thought they had dealt with the corner. You can see the frustration from his teammates as some make their way back to the centre circle with their heads to the floor.

There is no need to guess what was being said and thought.

Camilo Durán supplied the delivery, with Scales stretching to send the ball looping beyond Nico Mantl.

The centre-back admitted afterwards that he had simply been trying to get his effort on target.

The winner came after the Hoops kept a corner alive and put another delivery into the box; it’s clear that Ross Grant is having a good start to life at Celtic. He was wanted at Ibrox, but instead chose to move to the Scottish champions. 

Scales remained forward and made that second phase count, and the set-piece coach has clearly been working on this. For every set piece, he remained on the touchline for the following phase of play.

Celtic could not find another goal, but Kilmarnock could not undo the damage either. In the end, it’s the three points that matter.
