Chris Sutton insists this afternoon's Glasgow derby was "men against boys" as Celtic were beaten by Rangers.
Ryan Naderi's goal in the first-half was the only strike of the action as the hosts huffed and puffed at Parkhead before ultimately losing the fixture.
Sutton was unimpressed by Martin O'Neill's side as well as the manager's suggestions at full-time that the game was close when in reality, Gers dominated their hosts and deservedly took all three points.
"Celtic have got big problems. They were smashed by Rangers and that's a concern," Sutton said on Sky Sports.
"Knowing Martin, he'll be greatly concerned.
"I don't like to disagree with him but it wasn't a close game. There was a massive gulf between the teams. I can't actually remember a Celtic team getting such a doing at Celtic Park from a Rangers team, which happened today.
"It looked like Celtic were making it up as they went along.
"Rangers were better in every department.
"It was men against boys, it was the exact same as last week."
