Of all the decisive fixtures in the final round of European World Cup qualifiers, Portugal vs Switzerland was arguably the most tense.
Wales and Ireland's shootout for a play-off spot had a lot riding on it, but Tuesday night's main event had an automatic spot up for grabs, not just second place.
Both sides had been near enough perfect, with Portugal the only one of the two to drop points, which was obviously when they travelled to Switzerland, losing 2-0 back in February.
But, due to the fact that the Portuguese had a far superior goal difference, a win of any sort in Lisbon would mean they would be packing their bags for Russia.
The atmosphere was electric and the hosts matched it, winning 2-0 to send the fans wild.
An own goal from Arsenal cult hero Johan Djourou just before the half-time break was followed up by an Andre Silva goal in the second period.
In all fairness, Switzerland barely threatened, with the Euro 2016 winners deserving of their World Cup place.
One man who returned to the lineup after missing out against Andorra was Cristiano Ronaldo, who coincidentally broke the deadlock in that fixture.
The Real Madrid superstar was deployed on the right and he turned in a fairly average performance by his lofty standards.
Nothing he seemed to do came off and late on in the game, he produced a pretty embarrassing moment.
CR7 was put through by Inter Milan's Joao Mario and when faced with the prospect of just beating Yann Sommer, the serial goal scorer seemed to forget his enormous talent.
Ronaldo never really looks in control of the situation and his desperate attempt to delicately chip the keeper is almost laughable.
The miss also means that he failed to match Robert Lewandowski's record-breaking tally of 16 goals in qualifying, with CR7 stuck on 15.
However, he did record two more assists, so technically, he had a higher goal involvement.
Naturally, because it was Ronaldo, Twitter just had to tear into the former Manchester United man.
Next time Ron, just tuck it away without overthinking it, you know, like you usually do in Madrid.
