A fan-favorite Rangers pub has blamed the actions of some Celtic fans for two of their supporters getting stabbed in Rome.

The Louden Tavern, self-described as "The Quintessential Rangers Supporters' Venue", say that "lessons need learned" after the attacks in the Italian capital last night.

We told earlier how two Hoops supporters were left with non-life threating injuries after being stabbed at Flann O'Brien Irish pub by Lazio "ultras" fans ahead of tonight's Europa League match.

It's been reported that a group of masked thugs shouting "Lazio" ambushed fans outside the pub.

The Scottish Sun reports that a group of armed Lazio ultras, who had covered their faces with masks and scarves, ambushed the supporters outside the bar shortly after 11.30pm Rome time.

A witness told the paper how one fan was stabbed in the leg, adding: "They came out of nowhere. He was doing nothing wrong.

“They were shouting 'Lazio' and had masks on their faces."

But The Louden Tavern has now laid blame on some Hoops supporters for the attack.

They posted to their 50,000 Twitter followers: "Celtic have allowed a section of their support free reign and unfortunately the consequences of it are being suffered by most likely a normal fan.

"Lessons need learned."

Their comments come in light of Celtic chiefs issuing a warning to fans ahead of what is being described as a high-risk match.

Around 9000 travelling supporters were advised to "stay in large groups",  "keep a low profile" particularly in the evening and "avoid wearing club colours". 

Last week, Celtic responded to Lazio supporters' fascist salutes during a march through Glasgow's Buchanan Street with a banner of executed Italian dictator Mussolini hanging upside down with the caption "follow your leader".

The pub faced backlash online for their comments.

They later added: "Serious violence has no place in football. No one should go to a game of football and suffer serious injury.

"No one is siding with Lazio here".

Reaction to the post, one outraged Twitter user wrote: "Point scoring, eh".

However another added: "Hope the guy is ok, but the clowns in their support making banners celebrating the death of the leader of the most notorious and violent fans group was never going to end well. This was sadly predictable".

Celtic have since released a statement following the attack.

A spokesperson said: "We can confirm that two fans have been injured after being stabbed last night.

"Both are now in hospital and will receive every support from the club and the British consulate in Rome.

"Again we would strongly advise supporters to closely follow all guidance issued by the club."
