Kris Commons scored his first goal of the season in Celtic's 3-0 win over Rangers at Parkhead and then claimed it would be "devastating" if the Ibrox club were to drop out of the Clydesdale Bank Premier League.

Goals from defender Charlie Mulgrew and the Hoops midfielder gave the rampant champions a commanding interval lead against their administration-hit rivals, who could lose their place in the SPL if they are liquidated.

Striker Gary Hooper scored with a thumping strike soon after the break to seal the win which took Celtic 21 points clear of Ally McCoist's side.

Commons, who claimed his delicate chip over Allan McGregor was the "icing on the cake for me" revealed his views on the Old Firm fixture.

"They are the biggest games in Scotland if not around Europe," said the Scotland international.

"The fan base, the people who want to watch it on television, I think it is everything that is good about Scottish football.

"To not have a Glasgow derby would be devastating for Scottish football.

"From a fans' point of view, if Glasgow Rangers weren't in the SPL, what other game would you look at?"

Commons was well aware Rangers had won two of the previous three Old Firm meetings this season before today

"We knew that going into the game," he said. "If you are winning a championship and your local rivals have got one over you then it puts a little dampener on it so we had to set the record straight.

"We treated it like a cup final today. We got out of the blocks reasonably quickly and tried to impose our good passing and movement on the game and it didn't take us long to get in front.

"At half-time we wanted to go and get four or five.

"I thought we were playing really good football, but I think after the first 60 or 70 minutes we put in to try to get a good lead we perhaps took the foot off the gas a little bit.

"There were a few half-chances at the edge of the box for myself and Georgios Samaras and Joe Ledley's volley could quite easily have gone in, but it was tough afternoon, it wasn't a walk in the park.

"To score three goals and keep a clean sheet in any derby is a good achievement and the lads are buzzing.

"I can't wait for the last game of the season to get my hands on the trophy.

"It's one of my dreams playing for Celtic, to win the SPL title and no doubt I will enjoy the last game of the season."
