Liverpool chief executive Peter Moore visited an injured fan in hospital on Tuesday night after supporters were attacked ahead of the Champions League match against Napoli.

The Liverpool boss confirmed he was taking care of a supporter after a concerned friend posted to a supporters forum that Steven Allen had "collapsed at half-time due to significant blood loss sustained after being ambushed in a bar by Napoli fans".

"If anyone is in Naples or know of anyone in Naples and is not far from (Ospedale Cardarelli) hospital, please could they check on him," wrote Matty Johnson, who had not travelled to Italy.

Mr Moore later tweeted that he was "at the hospital with Steven".

"We will not leave him until we are comfortable that he’s fine, so can everyone stop worrying for now. Trying to get him seen by a doctor, but there’s a distinct lack of urgency here from the police and medical staff," he wrote.
