A 53-year-old Irish man attacked before last night's Liverpool match is in a critical condition in hospital.
Kick off time was scheduled for a quarter to 8 - but around 10 minutes beforehand an Irish man was attacked outside a local pub.
Witnesses say the 53 year old was hit with a belt.
Paramedics who were called to treat the victim believe he suffered head injuries.
He was taken to the Walton Neurological Centre where his condition is described as critical.
Police arrested two Italian men inside the stadium during the game on suspicion of attempted murder.
Today they're examining CCTV and appealing for witnesses.
Liverpool FC says it's appalled by the violence while UEFA has also released a statement:
"Uefa is deeply shocked by the vile attack that occurred ahead of Liverpool FC v AS Roma & our thoughts are with the victim and his family."
"The perpetrators of this ignominious attack have no place in football and we trust they will be dealt with utmost severity by the authorities.
"Uefa is waiting to receive full reports before deciding on potential disciplinary charges."
