Police investigating an attack on a Liverpool fan before the Champions League semi-final at Anfield are appealing for CCTV and camera phone footage.
Father-of-three Sean Cox, 53, from Dunboyne, Co Meath, Ireland, remains critically ill following the assault outside the stadium ahead of the first leg tie on Tuesday April 24.
Detective Inspector Paul Speight, of Merseyside Police, said:
Sean Cox remains in hospital in a critical condition at Walton Neurological Centre. Our thoughts are very much with his family who are going through an extremely tough time, and we want to bring anyone responsible to justice.
Fighting erupted near The Albert pub, close to the ground, shortly before kick-off, where it is believed Mr Cox was hit with a belt and fell to the ground at 7.08pm.
A friend of Mr Cox, Damien O'Reilly, a councillor in Co Meath, described him as a role model and cornerstone of the community and heavily involved in local Gaelic football.
In a statement, Mr Cox's family said he is "the most amazing and wonderful husband, dad, friend, son, uncle, and brother, and he has brought us all nothing but joy".
Two Italian nationals charged in connection with the assault are due to appear at Liverpool Crown Court later this month.
Footage in the area between 7pm and 7.45pm can be sent to the force's dedicated investigation team via Anfield.Incident@merseyside.pnn.police.uk
