Denmark stand between them and immediate progression but if Portugal can go all the way, it would be the first time since 2019, when they hosted the tournament, that they will have won it.
Key to those title aspirations is their captain, figurehead and talismanic leader, 40-year-old Cristiano Ronaldo.
As one of the best to have ever played the game, Ronaldo's place in the history books has long since been assured. However, one can't help but ask the question as to whether his inclusion in the squad is just an extension of a vanity project or if the numbers genuinely do back up the belief that he is still one of the best men for the job.
From a goalscoring perspective in the current competition he's certainly paid his way as five goals scored is just one short of half the total of 12 that the entire squad has managed in the competition to date.
Having hit the woodwork three times too, conceivably, he could have managed eight goals in his five total appearances in the competition which would've been a more than acceptable return for a player half his age.
Of his five scored in the 2024/25 Nations League, only one has been from the spot, which at least puts to bed, for now, the ludicrous argument that the vast majority of his goals come from 12 yards - albeit all five of them have been scored from inside the area.
Ronaldo needs to show his value in more than goals
Despite still being the player that is looked to for his match-winning capabilities, Ronaldo's aim these days is way off. In fact, a 38.9% shooting accuracy statistic is the second worst in the entire Portugal squad.
One could argue that the elder statesman is still getting in the positions to get his shots away in any event and the law of averages means that he will miss more than he scores. However, when the likes of Bernardo Silva and Joao Felix are posting figures of 100% and 83.3% respectively, it must be hugely frustrating to see a teammate still so revered when misfiring so badly.
Ronaldo has also missed five big chances in the competition so far, the most from a Portuguese perspective.
Of those Portugal players that have attempted at least five dribbles in the current tournament, Ronaldo's 60% success rate puts him joint top of that particular metric with Bruno Fernandes. Both have completed three dribbles, though Bruno is much more involved in general play as his 380 touches across his country's Nations League games is more than double his contemporary's 182.
Cristiano's passing accuracy of 85.8% reads as being in the top bracket too until you realise that only two other players in the squad have a worse output. His total of 127 passes is also well behind many of his colleagues including Ruben Dias (314), Vitinha (352) and Nuno Mendes (404).
Whilst it's ostensibly true that being stationed out wide on the wing or up top wouldn't necessarily lend itself to a player needing to be involved in the game as much as his teammates, he still has to provide value when called upon during 90 minutes.
Even if you take into account that Ronaldo is amongst a number of players to have been involved in at least 20 duels throughout the duration of the competition, it's safe to say that that's not really Portugal's forte. Only Bernardo Silva has a success rate of over 60%, and his 61.9% statistic is hardly anything to write home about.
Putting a foot in isn't something that you would normally associate with Ronaldo's natural game of course, so three tackles in five games is hardly a surprise. Far more worrying would be the fact that a player such as Ruben Dias has only made four in the same time frame.
It's time for Ronaldo to bow out of internationals
On the flip side of that particular argument, Roberto Martinez's side have been one of the cleanest in the tournament. No red cards and a team not having to revert to the dark arts is somewhat refreshing in this day and age. Indeed, only Bruno has more than one yellow card to date.
Aerially, where one might expect Ronaldo to still excel, the 40-year-old has surprisingly won just two from 10 headed duels, again amongst the worst in the squad.
Even Rafa Leao, whose aerial prowess hasn't necessarily been noteworthy in the past, has won three from three.
Using the same sample size, only Diogo Jota with three ball recoveries is worse than Cristiano's six, whilst Nuno Mendes with 28 and Bruno Fernandes with 23 lead the way in this regard.
Both forwards - Ronaldo and Leao - have also been caught offside four times each, the only two players to have done so more than once. Delaying their runs by just a split second would potentially ensure that the pair are able to garner more success in the final third.
Ultimately, Ronaldo's stated dream of Nations League glory is still alive and well, and Martinez clearly sees something in the Al Nassr man that he feels he can work with.
Perhaps it's his sheer motivational presence in the dressing room that can't be replicated and that in itself is arguably a good enough reason to keep him in the squad. After all, Ronaldo has continued to show that with the right mindset and dedication to the job at hand, anything is possible.
To be fair, he's far from the worst player in Portugal's squad too, but his influence is definitely on the wane - as might be expected for someone at 40 years of age.
It's clear enough that Ronaldo will see out the tournament in situ but looking at the numbers, Portugal would be doing themselves a huge disservice if they were to consider having him lead them into World Cup 2026.
In summary, regardless of whether they win the Nations League or not, the time has finally come for Cristiano to bow out gracefully whilst he's still, just about, at the top.
