LIVERPOOL fans travelling to Napoli next week have been advised not to leave their hotel other than to attend the match or wear the club colours.
Jurgen Klopp's side will face the Italian club in the Champions League group stages - but the fixture has previously been marred by fan violence.
Liverpool have liased Merseyside police to inform their supporters of the dangers of travelling to the match.
The club released a statement on their official website to advise fans how to act ahead of Tuesday's clash at the Sao Paolo Stadium.
Fans have been urged to use the allocated shuttle buses to get to the stadium instead of making their own way.
Transport to the stadium from Stazione Marittima will be free for all fans with a valid match ticket.
Supporters have told to remain in their hotels to eat and drink and not to congregate in public areas.
Club colours should be ditched in order to blend in with the crowd and they should check they are wearing the right sized belt.
Similar warnings were issued when the club's clashed in last year's competition - but several incidents still occurred outside of the ground in Italy.
At least six Liverpool supporters were injured and three Italians were charged with attempted murder after the two sets of fans clashed in 2010.
And a Napoli fan was reportedly hospitalised after he was attacking following Liverpool's 1-0 home win in December.
But the problems don't just lie outside of the Sao Paolo Stadium.
Napoli boss Carlo Ancelotti is furious after finding out the club's dressing rooms are a still construction site just days before the match.
