St Johnstone manager Derek McInnes believed a bad refereeing decision cost his side a precious point in the 2-1 defeat at Aberdeen.

The Saints had come back from a goal down to equalise through Liam Craig before Lee Miller won a penalty in the 83rd minute following a collision with defender Danny Grainger.

The Dons striker netted from the spot to give the Dons their first win since the middle of September - but McInnes felt his player was harshly penalised.

He said: "I felt there was definitely a foul on Danny Grainger in the build-up. Lee Miller grabbed Danny and spun him to gain an advantage in the box.

"The ball was played into the area 10 yards away from the incident and what has happened is Danny has tried to make up the ground after initially being fouled and, as he has run back, Lee has stopped and Danny has nowhere to go and it is a coming together.

"The ref has said it was a push and a pull which it clearly wasn't. He has got it wrong and the linesman should see the foul by Lee Miller."
