British police chiefs hope the "impeccable" behaviour of England and Wales fans during last week's match will continue as the two teams gear up for crucial final group games.
Security has been boosted ahead of Wales v Russia in southern France on Monday, following violent scenes in Marseille and Lille, as UK investigators work to identify Russian hooligans who attacked England fans, as well as English troublemakers.
England go into their final Euro 2016 group game knowing that anything but defeat to Slovakia in Saint-Etienne will guarantee their place in the next round.
Fans have been arriving in the French city over the last two days, where 18 years ago Michael Owen scored his famous goal against Argentina in the 1998 World Cup. A party atmosphere was quickly established in a central square as supporters strung up dozens of England flags.
Mingling with locals and with a police force prepared to remain at a distance, England fans engaged in games of football as well as watching a big screen and dancing to a DJ blaring out '90s Brit Pop.
In Toulouse, where Wales will take on Russia, more than 600 extra police officers will take to the streets, on top of the 1,500 already due to work, after the match was upgraded to high risk. There will be a midnight curfew in the city, and a ban on glass bottles.
National Police Chiefs' Council lead for football policing, Assistant Chief Constable Mark Roberts, said: "We remain aware of the events in Marseille and this has inevitably played a part in the planning of forthcoming games. The French police have taken positive measures in preparing for this match (Wales v Russia) and we will continue to liaise with them regularly.
"The investigation team has been working tirelessly to identify those who were involved in disorder and also those who were seen to attack English fans. We will pass this information on to the French police to assist in their ongoing investigations and to help prevent any further disruption.
"It should be noted that the behaviour of the Welsh fans throughout Euro 2016 has been exemplary, especially in the recent game against England where there was little segregation and a last minute winner.
"Both sets of fans behaved impeccably throughout the game, as have Northern Irish supporters during the group stage. We hope this will continue and they all enjoy the rest of the tournament."
In the build-up to Monday evening's action, captain Wayne Rooney said he wanted the Football Association to back England boss Roy Hodgson with a new deal, saying the players wanted him to stay.
This came after outgoing FA chairman Greg Dyke appeared to suggest that a semi-final appearance would see the 68-year-old stay on, while a quarter-final exit might still be enough if the team played - and bowed out - in an acceptable fashion.
England come into the match against Slovakia on a high after their last-gasp victory over Wales in Lens, after they went behind from a Gareth Bale free kick.
