Thousands of fans have come from Belgium to Glasgow to watch the World Cup qualifier at Hampden.
And, as Glasgow braces for an influx of visitors, the game means one thing for police - high visibility.
From early on Friday officers were deployed to patrol the Merchant City and the area around Scotland's national stadium.
Intelligence suggested more than 7500 Belgians were expected for the game - more than had bought match tickets.
About 2500 were expected to gather in the Merchant City fan zone, which was packed from 4pm to 6.30pm.
From there, fans were ushered to Central Station and helped to travel out to Hampden.
The clear stategy by police and council bosses helped ensure disruption for fans and Friday-night revellers was kept to a minimum.
And the good nature of it all was backed up by the figures - just eight arrests from the match, all for minor offences.
Before Friday night's game, dozens of fans had gathered in Cathcart Road to enjoy pre-match hospitality. The street was, to quote one officer, "log-jammed" with fans.
Although good natured, many were drinking in the street - an issue that must be addressed by police.
Chief Inspector Alan Porte said his teams were not heavy-handed but used common sense.
He said: "We can't reasonably expect fans from Belgium to understand our bylaws and that we do not allow drinking in the street.
"However, we still need to maintain a sense of order so officers will issue warnings to anyone found drinking outdoors and drinks will be taken and poured away.
"Of course, if warnings are not heeded then officers will move to make an arrest - though we would prefer to avoid that."
As crowds gathered for the game, police in pairs were stationed around Hampden with mounted officers surveying the crowd.
The horses come from their headquarters in Stewarton in Ayrshire to police major events such as the Hearts vs Liverpool and Hibs vs Celtic games.
They are used for crowd control not just at football matches but at events such as recent Scottish Defence League rallies.
The 22-strong unit can also be seen patrolling city centres and local communities - anywhere where high-visibility policing is needed.
In fact, it is their high-visibility that make the horses such an asset at games.
From their lofty position in the crowd, mounted officers can survey a much larger area than foot patrols.
They can also be clearly seen from the ground, detering crime and reassuring crowds.
Although security is tight on match days - particularly with a large international crowd - Hampden is far from one of Glasgow's toughest beats. The area around the national stadium had just one serious assault, one robbery and two indecency offences last year.
Statistics do not say which if any of these serious matters co-incided with football matches or concerts.
However, police have always hammered down on public drinking and urinating by football fans and this is reflected in the figures.
There were 220 cases of public drinking in Hampden last year, up from 192 the previous year.
Where there are high levels of public drinking high levels of public urination often follow
The figures show last year there were 65 incidences of public urination, up 10 from the year before but arounf half the level of 2006-2007.
Figures for possession of drugs are also relatively high in Hampden, with 114 cases last year.
This, police insiders stress, suggests heavy-stop and-search activity aimed at those attending events in the area.
The largest increase of any crime in the area is that of theft from a motor vehicle.
In 2006-2007 the number of thefts from vehicles stood at three, rising to 12 in 2011-2012 then 26 last year.
Although police are more pragmatic about street drinking during games they are far from condoning the crime.
In fact, as we told in Saturday's Evening Times, police have intensified their crackdown on drunken yobs with a dramatic rise in the number caught drinking or urinating.
Nearly 20,000 fixed-penalty notices - a rise of 18% - were issued to people who drank outdoors in 2012-2013.
Chief Inspector Porte added: "The visiting fans from Belgium were in jovial mood, they were very good-natured and mingled with the Scotland fans.
"The crowds that gathered in the fan zone in the Merchant City were then escorted by the police to Central Station to make sure they were safe.
"After the match they came back into town to experience everything Glasgow's night-time economy has to offer.
"Scotland fans have been in good humour and the night has been a real success for everyone involved in keeping the city safe."
