After the full-time whistle Cape Verde’s players formed a huddle around their head coach, Bubista, eyes straining at the tiny moving images on a mobile phone. They sought the certainty that a dream had come true and, when the outcome nearly 1,000 miles away in Guadalajara was confirmed, erupted in unfathomable joy. Dailon Livramento, the centre-forward, leapt on to the back of his teammate “Diney” Borges. Everyone in view grabbed the nearest person to embrace and then came all the flags, the islands represented by their 10 stars made famous during one of the World Cup’s most compelling underdog stories in decades.

One of them was waved in the stands by Ana Cândida Évora, the mother of their remarkable goalkeeper, Vozinha. Others made their way on to the pitch and what a sight it was when the entire squad, visibly buzzing to a man, stayed still for long enough to pose for photographs in front of a disbelieving support. They drummed and sang into the night because never has the most formidable of tasks seemed so glorious. Cape Verde, the country of 530,000, will take on Lionel Messi and Argentina in the last 32.

• 41-year-old heavily criticised after DR Congo draw

• ‘It felt like I’d already retired from football,’ he adds

Cristiano Ronaldo savoured the end of a “difficult, dark week” after scoring twice in Portugal’s 5-0 rout of Uzbekistan and becoming the first player to find the net in six World Cups.

Ronaldo and Portugal had come under heavy criticism after a flat draw against Democratic Republic of the Congo. There had been a particular spotlight on the 41-year-old Ronaldo, who had not scored in 10 major tournament games before Tuesday’s fixture. There have long been question marks over his continued ability to lead Portugal on this stage, but after the final whistle he shouted into a television camera: “I’m back, I’m back.”

Golden oldies fighting for the golden boot? Let us not get ahead of ourselves. But it will do Cristiano Ronaldo’s ego no harm that he is off the mark at this World Cup, particularly in light of Lionel Messi’s voracious appetite to stoke fires that started long ago. Two first-half goals gave Houston’s public what they came for and laid an unfortunate run to rest. Until this contribution to what quickly became a leisurely non-contest, Ronaldo had not scored in 10 major tournament matches.

Thank goodness, then, for an Uzbekistan defence that would have struggled to hold firm in a Masters game. There could have been no better opponent to help Ronaldo get his eye in, Nuno Mendes’ free-kick, an Abdukodir Khusanov own goal and Rafael Leão’s late adornment emphasising the point. Fabio Cannavaro’s players could not get near opponents of this level.

It turns out Sweden do not have a monopoly on old-fashioned centre-forward play. They were schooled in it here by Brian Brobbey, who was brought in by Ronald Koeman to give the Netherlands’ attack a focal point and swiftly made his under-pressure manager resemble a genius. Brobbey scored twice in the opening 17 minutes to pave the way for a crushing win, proving impossible to handle with a cocktail of strength, touch and finishing.

Koeman had criticised his own decisions after Sunday’s 2-2 draw with Japan, lamenting substitutions that failed to pay off. This time he could, if the mood took him, pat himself firmly on the back. There was yet more to enjoy in the contribution of Crysencio Summerville, who sparkled after his half-time introduction. Summerville finished unerringly late on to complete a rout that leaves Sweden dizzy from finishing on different ends of the same scoreline.

The clock was about to hit 83 minutes when Roberto Martínez rolled the dice one last time. His team certainly needed extra movement up front so it hardly confounded logic that Gonçalo Ramos was stripped and ready. What made less sense was that Vitinha departed while Cristiano Ronaldo, peripheral save for two earlier half-chances, remained on and slogged his way towards the end of a draw that could check Portugal’s summer ambitions.

Ronaldo’s baying followers, swathes of them with local accents and wearing his No 7 shirt, had done their best to cajole a meaningful contribution from their idol but ultimately they had to settle for being under the same roof. Perhaps they expected a repeat of Lionel Messi’s staggering performance the previous night but Ronaldo did little to assuage concerns that his presence, once glorious, is nowadays a dead weight. The watching Gianni Infantino could have been forgiven for wondering whether Fifa’s contortions in freeing him from suspension for this game had been worthwhile.

The net rippled and Curaçao’s bench exploded in every conceivable ­direction, their giddiness underpinned by a lucid awareness of the goal’s place in history. Livano Comenencia had just equalised against Germany and an island of 158,000 inhabitants, represented here by an accomplished group born almost entirely in the Netherlands, could revel disbelievingly in a moment it had dreamed of.

Reality eventually bit, Julian Nagelsmann’s side declaring on seven and easily avoiding an embarrassment that would have outdone their group-stage exits in the previous two World Cups. They will surely reach the knockouts this time and could have made absolutely certain by adding several more. Nagelsmann will be pleased that threats emanated from across the pitch, half a dozen different scorers bearing testament to that, but it should go without saying that more accurate tests of strength await. Kai Havertz, rounding things off neatly late on with his second goal, will hope to be similarly efficient later on.
