Ferguson: 'It hurts'

“Another Old Firm horror show. It’s a struggle to find the words to describe it,” the Rangers legend said.

It was the sight of Celtic players pointing and laughing at an empty Rangers end, that had been mostly cleared before full-time, that really got to Ferguson.

“Watching Celtic players pointing over at the Rangers end when there’s nobody there and laughing, it hurts,” Ferguson added.

“I am speaking from the heart, it’s the most difficult thing to assess what happened so soon after having to sit through it.

“As a Rangers fan it’s difficult to watch Mikael Lustig putting on a policeman’s hat to celebrate a goal.”

The concern for Ferguson, who won five Scottish titles with Rangers, is he doesn’t expect the players to be cut up by the embarrassment.

“I hope it’s hurting those guys in the dressing room but that’s the worrying thing, I don’t think it really hurts them,” he continued.

“Were there choice words said at full-time? I doubt it.

"There should have been heads rolling, people should have been squaring up to one another, boys should be getting called out.

“That’s what happens with teams who have a winning mentality, people who don’t deliver get called out.

“But I worry nothing has been said, it’s straight into the shower and straight onto the bus.”

For someone who was present when the Old Firm derby truly was a ferocious contest, it pains Ferguson to see the club he adores on the losing end time after time.
