People arrested for being drunk and disorderly in part of Liverpool city centre during the World Cup could get a criminal record, police have warned.
A football safety zone will be in place for England matches and on Friday and Saturday nights.
Anyone arrested for being drunk and disorderly or involved in disorder will be given a conditional caution instead of the usual fixed penalty notice.
A conditional caution stays on a person's permanent record.
If they refuse to accept the caution they will be charged, police said.
Anyone given the caution will also be banned from the zone - in Concert Square, Wood Street and Slater Street - for the rest of the tournament and will have to attend an alcohol intervention programme.
Chief inspector Louise Harrison, of Merseyside Police, said: "Residents and visitors to our city should be able to enjoy what it has to offer in a safe environment and the World Cup is a great opportunity for people to watch the games in our many bars and pubs.
"We recognise that during football matches such as this, excitement can bubble over. We want people to think on before they cross the line - is one night of drunken behaviour really worth ruining your permanent record?
"We're taking positive action and will have extra officers in and around the city on match days. We want to get the message across that disorder and violence will not be tolerated in our city."
The zone will be launched on Friday and run for the duration of the World Cup.
