FORMER Celtic star Kris Commons has slammed the Rangers fans who lobbed bottles onto the Ibrox pitch yesterday.

He has urged the Light Blues to dig out those responsible, as he insisted that some of their fans can't behave when at games.

The game finished 2-1 to the Hoops, thanks to goals from Tom Rogic and Cameron Carter-Vickers.

The result fired Commons' old side six points clear at the summit of the Premiership with only six games left.

It was certainly a hammer blow to Rangers' hopes of retaining the title.

However, the headline news in the aftermath of the game was the shards of broken glass found on the pitch right after half-time.

On top of this, a Celtic staff member required stiches after being struck by a missile.

And Commons was disgusted by what he saw.

He wrote in the Daily Mail: "Those missiles which pelted Joe Hart's penalty box and a Celtic member of staff were quite obviously thrown from sections of the stadium housing home supporters.

"Rangers have simply got to find the culprits and ban them for life.

"Seriously, what sort of idiot goes to a football match and thinks it's a good idea to throw bottles on to the pitch?

"I'm not convinced a glass bottle would actually smash on a grass pitch unless it was thrown from a truly extraordinary height.

"So, unless it shattered off a goalpost, you've got to consider the possibility that someone has gone to Ibrox yesterday with a broken glass bottle in their pocket, with the intention of throwing the shards on to the pitch.

"Rangers fans can't behave themselves at the best of times. They went down to Manchester in 2008 for the Uefa Cup final and caused mayhem.

"Then, after winning the title last year, they turned George Square into a riot zone. And these were supposed to be the good times?

"Rangers fans have a chip on their shoulders from the financial meltdown of 2012.

"They are very quick to play the victim card and seem to think the rest of the football world owes them a favour.

"Or that they can get away with blue murder and do whatever they please without any consequence.

"Now, admittedly, it would be wrong to tar them all with the same brush.

"A couple of my closest friends are Rangers fans and we have great banter together. It's all good-natured, knockabout stuff.

"But there is another element to a section of the Rangers support who are, frankly, a disgrace. They have absolutely no class whatsoever.

"You could also see quite clearly on the TV cameras that Celtic winger Jota was having coins thrown at him as he went to take a corner.

"In the interest of balance, let me be clear on this. Celtic have their own issues in this area.

"The Green Brigade have stained the club's reputation at various points in recent years.

"But for someone to intentionally throw a bottle or broken glass on to a football pitch?

"Come on, that's surely a new low. That's actually worse than what we saw at George Square last year.

"It's now up to Rangers to engage with police to ensure the culprits never again set foot inside a football stadium."
