Sky pundit James McFadden reckons Allan McGregor will be unhappy with his efforts to stop Celtic scoring their equaliser seventh minute equaliser.
The Hoops were rocking after a fast Rangers start when they broke up the park and scored with their first attack.
McGregor saved Reo Hatate’s weak-looking effort but palmed the ball straight to Tom Rogic who slotted home.
And McFadden reckons the 40-year-old won't be too happy when he reviews the footage.
Asked if McGregor could have done better,he told Sky Sports: "Maybe. I think it's a terrific run from Callum McGregor.
"The defence don't clear the box. They are watching the ball and Tom Rogic is just hanging in a great position at the back post to finish it.
"I think when Allan McGregor sees that back, he will be disappointed he hasn't been able to potentially catch it, and get it clear.
"Having said that, you can't leave a guy like Tom Rogic with that much space in the box."
