EXTRA police patrols will be on the region's streets on Sunday ready to crack down on any outbreaks of football-related hooliganism.
Pubs across the region are expected to be packed with fans watching England's eagerly-awaited Euro 2004 game with France on TV.
But police in North Yorkshire insist they want everyone to enjoy the tournament and will have extra patrols out across the county.
Deputy Chief Constable Roger Baker said: "We won't tolerate any kind of disorder, and we will have the resources in place to deal with it firmly and decisively.
"What we hope for is a good-humoured event, with fans enjoying both the football and the social side of viewing together and - especially - we hope that non-fans will not be upset or frightened by any fans misbehaving."
Mr Baker said: "Sunday is a big day for English football and we expect large numbers of supporters to be in lively mood in North Yorkshire's pubs, clubs and bars.
"We want them to have a great evening, win or lose, and we want them to respect other people while they do it."
The police have been working with licensees in preparation for Euro 2004 to compile information on where the biggest crowds are likely to gather.
They have also been advising publicans on matters such as using large-scale TV screens, the prevention of overcrowding and the use of plastic glasses.
Officers have also worked with closed-circuit television (CCTV) operators to ensure cameras pay particular attention to potential trouble spots.
Mr Baker added: "I see no reason why people should behave badly on Sunday even-ing, but if anyone does step over the line they can take it from me that we will be there to deal with them."
Cleveland Police also intend having extra officers on the streets to deal with any potential trouble.
Police in County Durham said they had no plans for extra patrols, but are planning a high-profile drink-drive campaign ahead of the even-ing match.
A spokesman said: "Everybody has become used to important matches being watched by lots of people in pubs.
"In the unlikely event of any trouble, we'll respond to it as we would in normal circumstances."
