A former police constable has told the Hillsborough inquest the match commander 'didn't offer true leadership at any stage' as the disaster unfolded.
Former PC Trevor Bichard said Chief Superintendent David Duckenfield was 'a fish out of water'.
He had replaced a more experienced senior officer in charge of the police operation only days before the FA Cup semi-final at the Sheffield ground.
The former constable was with Mr Duckenfield in the control box as the crush started at the Leppings Lane terrace.
PC Bichard monitoring CCTV around the ground.
He told the new inquests in Warrington 'David Duckenfield was a manager not a leader'.
The jury in Birchwood also heard that complaints were made about problems with police radio transmissions more than an hour before kick-off.
'Without communication there is no control' said Mr Bichard.
He said there were no messages coming from radios around the perimeter fence where fans had started trying escape the crush that killed 96 Liverpool fans.
Families of the 96 Liverpool fans who died in the Hillsborough disaster have finally received justice.
