Chris Sutton has slaughtered Rangers forward Fabio Silva and referee John Beaton after the decision to award a penalty against Celtic.

The former Parkhead striker blasted the "embarrassing climb down" from official Beaton and he accused Rangers' Silva of "cheating" in an astonishing rant.

Sutton - on co-commentary for the match - had saluted Beaton for his initial decision to book Silva after he went down in the box under challenge from Alistair Johnston.

However, Nick Walsh called Beaton for a pitchside review with the whistler changing his mind to give a penalty kick.

Sutton said: "He's been an embarrassment. Throwing himself around all afternoon. It's really good to see. That's called cheating. John Beaton quite right to give him the yellow card.

"He's already on his way down. This would be an embarrassment."

The Celtic hero then added: "This would be embarrassing if he awarded a penalty. He's already on his way down. You shouldn't be rewarded for cheating.

"There has to be sufficient contact. Is this a clear and obvious error? Of course it isn't.

"It's an embarrassing climb down from John Beaton. It really is. Dear me."

On X, formerly Twitter, Sutton posted: "Incredible game. Great advert for Scottish football.

"Celtic controlled the first half and should have been out of site. The Rangers penalty award rewarding Silva for diving was embarrassing and changed the dynamic. Idah’s goal sensational as was Matondo’s leveller…"

Kenny Miller - also on Sky Sports duties - added: "He's done it too many times. This must be the fourth or fifth time that he's thrown himself down on the ground. There is very little contact, if any."

"Listen, his right boot is across his knee but he also touches the ball. There is no doubt he's gone down. It's not the contact that has led him to go down."
