Albion asked UEFA to film their fans being targeted by Roma counterparts at the Stadio Olimpico.

The club issued a statement during the 4-0 defeat reporting bottles, coins and lighters were being hurled into the away section.

Now chief executive and deputy chairman Paul Barber has revealed UEFA delegate Karl Espen Eriksen was taken to the corner of the Curva Nord, where away fans were accommodated, and shown the scenes as they happened.

Barber said he was proud of the way Albion supporters behaved in the face of provocation.

He also stressed the vast majority of Roma fans and locals were very friendly, both at the stadium and around the city.

But he expects to see action taken over the missile-throwing incidents.

In an interview with TalkSPORT, he said: “Unfortunately it has been happened for years and years in football.

“If I go back to my England days 25, 26 years ago, we were witnessing incidents like this even then.

“All we can do, and we have done, is to report it to the local authorities and the police, to UEFA.

“We actually took the UEFA delegate to the corner of the pitch to witness things being thrown at our fans.

“Our security staff literally led the UEFA delegate down to exactly where it was happening, asked him to film and take notes and we will see what happens.

“This gets reported time and time again and yet, time and time again, it continues to happen.

“I don’t know what the consequences will be for Roma.

“It’s sad because their executive team, their chief executive, their board are very nice people, very concerned about what happened and disappointed in their own fans, certainly small numbers of them.

“But this happens too often and, unfortunately, English fans are far too often on the receiving end of it.

“And yet the smallest discrepancy at one of our stadiums in England and UEFA come down on us like a ton of bricks.”

Two Albion fans were attacked in the city the night before game.

Barber said it was “really important” Albion fans do not seek any sort of revenge when Roma and their 1,500 fans come to the Amex on Thursday.

Despite the incidents, travelling supporters appear to have had a fabulous time over the last few days.

Social media has been flooded with photos and videos from many fans recording the trip and the mood was upbeat over everything but the result on the way home.

Barber said: “It’s not a night to forget because it is still a momentous time in our club’s history.”
