Liverpool fan Sean Cox remains in a critical condition after being attacked before the Champions League first leg tie on April 24.
Cox, a 53-year-old businessman from Dunboyne in Ireland, suffered serious head injuries in an incident outside Anfield and is being treated at the Walton Neurological Centre.
Fighting erupted near The Albert pub, close to the ground, shortly before kick-off, where it is believed Cox, attending the match with his brother, was hit with a belt and fell to the ground at 7.08pm.
Two Italian men have been remanded in custody after appearing in court charged in connection with the incident. The case was sent to Liverpool Crown Court, where both men will appear on May 24.
Police investigating the attack are appealing for CCTV and camera phone footage.
