Sir Kenny Dalglish has hailed referee Bobby Madden for his performance during yesterday's Old Firm derby at Ibrox.

The referee made a huge decision when he ordered Celtic defender Nir Bitton off the park for hauling down Alfredo Morelos, which he deemed to have been the denial of a goal scoring opportunity.

Dalglish reckons the whistler got the big call correct and he was impressed by his overall display.

Speaking in the Sunday Post, he said:"Bobby Madden has dominated much of the post-match conversation and debate over his red card for Nir Bitton.

"Well, I believe the referee called it absolutely correctly.

"My view on it is based on three factors:

"1 – Where the foul took place.

"2 – The manner in which he fouled Alfredo Morelos, namely wrapping his arms around the Colombian. There was no attempt to play the ball.

"3 – Morelos would have been inside the area with one touch and able to get a shot in on goal.

"Yes, you can argue that Kris Ajer was going to cover the ground and get across. That’s the point Neil Lennon made in his interviews after the game.

"But there still wasn’t enough evidence there to suggest that the referee got it wrong.

"But there was enough there that made it difficult for Madden not to send off the Celtic defender.

"I’m not saying that Morelos would have scored. However, that’s not the point. The fact is he was denied the chance of a goal-scoring opportunity.

"Overall, I think the referee handled the game very well."
