Police are increasing the numbers of officers on patrol in Lynn and across Norfolk this weekend for the first England Euro 2016 match.
They have appealed to licensees to take steps to retain order and ensure responsible drinking.
Drivers have also been warned of additional drink-drive checks throughout the tournament, including in the mornings following matches.
Inspector Ed Brown said: “We want everyone to enjoy Euro 2016 and but want to remind people to be considerate and tolerant to others. We’re reminding licensees of the importance of only running responsible promotions that do not encourage drunkenness.”
England faces Russia in its first match of the tournament at 8pm on Saturday.
With an increasingly multi-cultural society in Lynn, Insp Brown said police were aware of the possibility of racial tensions during the tournament, but had no reason to think it would be an issue.
Normally on a Saturday night there would be a public order team consisting of two sergeants and 10 constables. This weekend, on top of that there will be a third sergeant and another six constables.
The extra staffing is mainly possible through reallocation of rest days, Insp Brown said, minimising the cost to the public purse.
The Maltings Q Club, in Page Stair Lane, Lynn, is expecting double the number of patrons to a usual Saturday night, but is well geared up with extra staff and doormen - as is usual when there are is a big sporting event.
Amanda Springall, manager, is confident the night will go smoothly. She said: “We get a good crowd in here.”
Donna Crawford is general manager, at The Gatehouse, Lynn, where the match will also be shown - and they are offering a special football shaped burger bun. She said there are plans for future matches for revellers to win drinks but staff would be vigilant to ensure everyone stays safe.
She said: “It’s just a bit of fun.”
Chief Inspector Kris Barnard, head of Roads Policing in Norfolk, said: “There are some mid-week matches and late kick offs during the tournament and people need to be aware that the next morning they may still be over the limit.”
