There will not be a more one-sided affair all tournament.
Spain, the 2010 winners, are off to a convincing and ruthless start at a World Cup in which two of their rivals to go all the way have already been humbled by minnows.
But there was never a doubt about this result at Al Thumama Stadium from the moment Dani Olmo opened their account with a sweet finish in the 11th minute.
Marco Asensio made it 2-0 with a clinical first-time finish 10 minutes later and Ferran Torres scored a double of his own before Gavi became Spain's youngest scorer at a World Cup with a volley off the outside of his right boot.
Marc Soler added the sixth a minute from the end of normal time and Alvaro Morata added further gloss.
By full time Luis Enrique's team had enjoyed more than 80 per cent possession, goalkeeper Unai Simon did not have a single save to make and they completed more than 900 passes from a little more than one thousand attempted..
Here are the talking points...
1. So much for the goal concern
The biggest fear for Spain in advance of this tournament was whether they could convert their chances - especially if former Chelsea man Morata was leading the line. (He ended up being the first man off the bench early in the second period.)
Turning ball dominance into goals has been an issue dating back to their peak a decade ago. Not so here.
With half an hour on the clock, the front three had scored a goal each, making it just the second time in history that they have scored so many in the first half of a World Cup game.
Another three followed in the second period and the eight additional minutes shown immediately after Soler's effort was an additionally cruel blow; more than enough time for Morata to make it seven.
It was all strikingly ruthless, their foot not taken off the pedal once.
2. Midfield trio dazzle
This is a unit that has everything.
How far can Spain go at the World Cup? Have your say in the comments below.
With Sergio Busquets orchestrating from deep behind Pedri and Gavi, who at 19 and 17 have a combined age not too much older than the 34-year-old Barcelona veteran, there were moments where even for viewers the passing and movement was a blur.
It was also helpful that two-thirds were removed with a third of the game still to play such was Spain’s degree of comfort, keeping them fresh for what is to come next.
And then the one who remained made history in becoming the country's youngest goalscorer at a World Cup with a sublime fifth.
3. Germany concern
The initial shock of Germany’s defeat to Japan will have started to subside as Spain began to coast but when Hansi Flick and his players begin analysing the performance of their next opponents - at 7pm on Sunday - they will be hit by a sense of fear.
If Luis Enrique’s team are anywhere near as ruthless against the 2014 champions, then it will be a case of auf wiedersehen for a second straight World Cup.
4. Manchester City pair untested
Rodri got the nod at centre-back alongside Aymeric Laporte and even for Manchester City players accustomed to dominance, they will rarely have experienced such a comfortable outing.
5. Costa Rica get off to terrible start
What can you say about a team that was outclassed from first minute to last without even playing that badly? They were simply inferior to their opponents in every single department.
A starting XI with seven players aged 30 or over were chasing shadows for long spells, barely able to get a touch of the ball as those in red formed triangle after triangle around them.
It is nothing to be ashamed of and at least they got the hardest game out of the way first…
