If Portugal, by some miracle, are crowned champions of Europe next Sunday, it will be an achievement to eclipse even Greece’s triumph against the odds at the equivalent tournament in 2004. Denmark’s victory from the beach in 1992 will not compare, either, nor various Italian World Cup successes that always seem to come when their domestic game is in disarray.
For a Portuguese win in Kiev would be, in essence, the work of one man. Cristiano Ronaldo would have won the 2012 European Championship.
Not literally, but metaphorically.

Take him away, and it isn’t just that Portugal would not be in Wednesday’s semi-final with Spain; they would not be at the party, full stop.
No narrative here is quite as mesmerising as Ronaldo’s quest for glory. We have to search through almost three decades for a precedent, and to another figure who polarised opinion. This is Ronaldo’s 1986 World Cup; and he is this tournament’s Diego Maradona.
For Portugal to win here, overcoming first Spain and then in all likelihood Germany in the final, it is going to take the greatest feat of individual influence since Maradona made Argentina champions of the world in Mexico.
Sometimes an individual is stronger than the whole: Robin van Persie propelled Arsenal into the Champions League last season and Matt Le Tissier spent his career keeping Southampton up, but it is hard to remember the last time a country went so far into a major international event on the instincts of one majestic player.
Portugal squeaked here by the narrowest margin as it was: finishing second in qualifying Group H on goal difference from third-placed Norway.
The campaign began badly. Portugal drew 4-4 with Cyprus at home, then lost away in Oslo, both without Ronaldo.

At this point Carlos Queiroz, Sir Alex Ferguson’s former assistant at Manchester United, was sacked as coach and replaced by Paulo Bento, since when, the story goes, Portugal have never looked back.
Yeah right. Portugal could have been coached by Fray Bentos - it means Friar Benedict and, yes, he did exist - and it wouldn’t have made the slightest bit of difference without Ronaldo’s return. Undoubtedly, Bento is getting more from his best player than Queiroz did and for this he deserves credit - but the fact remains that without Ronaldo he would have been powerless.
Portugal, like Manchester United, like Real Madrid, are transformed by his presence. There is nobody quite like him in the game today; no player who can hit a shot that just by its flight identifies him as the shooter.
The ball looks different when Ronaldo strikes it, taking on a unique yet familiar trajectory that starts low, rises, and then sharply dips like a bucking stallion.
The greats have contributed turns and tricks to football’s evolution but Ronaldo is arguably the first player in history to as good as trademark a talent as commonplace as shooting. Ferguson insists it’s only practice.
He must spend hours.

So, in this campaign, Ronaldo’s return coincided with Bento’s appointment and in the next 12 competitive games - eight qualifiers, four in these finals - Portugal have lost once and he has scored 10 goals and made three others.
Remove him and, without doubt, Norway would have finished runners-up to Denmark and played Bosnia-Herzegovina for Portugal’s place.
Teams featuring Ronaldo, however, do not miss out on goal difference. Manchester United would have won the Premier League last season had he still been at the club. So having dragged Portugal east, he has steered them out of the group (both goals in a 2-1 win over Holland) and through the quarter-finals (the only goal of the game against the Czech Republic). It has been a tour de force, an act like no other in world football right now.
Lionel Messi is surrounded by great players wherever he goes. Yet the moment Helder Postiga - 12 appearances for Tottenham Hotspur in 2003-04, two goals, sold after 12 months at a loss of £3.63m - appears to lead Portugal’s line, it is obvious the task Ronaldo faces.
His match-winning attempts are almost comical in their desperate intensity. He has had 29 shots in this tournament - 14 on target - which is more than Greece over four matches. Approximately every 12.5 minutes, Ronaldo has a crack. You would, too, if Postiga was your match-winner.
Of course, Maradona’s statistics from 1986 are simply mind-blowing.

He played every minute of every game and of Argentina’s 14 goals, scored five and made as many, having a hand in all three in the final. He attempted or created more than half of Argentina’s shots at goal, made 90 dribbling runs (three times more than any other player) and was fouled 53 times (winning twice as many free-kicks as any rival).
His second against England was tagged the goal of the century and a statue celebrates it outside Mexico City’s Azteca Stadium.
Ronaldo has a way to go before matching that roll of honour, yet time has also helped Maradona’s legend grow. It is now said that he was the lone talent in Argentina’s World Cup-winning team, but he is not as isolated as Ronaldo is now.
Argentina 1986 would have murdered Portugal 2012. They were not a stellar side, and Maradona’s gift would have eclipsed many far greater, but were better than is widely recalled.
Argentina let just five goals in over 630 minutes in that tournament and kept three clean sheets.
Oscar Ruggeri is still regarded as one of the greatest defenders the country has produced.
Jorge Valdano had won a league and UEFA Cup double that season with Real Madrid; six of the Argentina starting 11 in the final had won the Copa Libertadores, the highest honour in South American club football - and Maradona wasn’t one of them.
Three and easy: Ronaldo's goals saw off Holland and Greece
What is Ronaldo working with by comparison?
Some fine players, not least Joao Moutinho, but their worth without him was revealed when the qualifying campaign began.
Drawn in the toughest group here, with Germany, Holland and Denmark, few expected even Ronaldo’s inspiration to be enough to get Portugal to the knockout rounds.
And it looked that way, at first, with the pressure at its height.
Facing Germany in the opening game, it must have appeared a daunting task to thrust this team into the later stages.
Maybe this is why Ronaldo started slowly, improving as the tournament wore on.
The final group game with Holland was a straightforward knockout, so too the quarter-final against the Czech Republic. And knockouts he can influence simply by being the greatest player on the field.
Orchestrating the entire campaign, a run of six matches viewed uphill from the foot of the toughest group, must have appeared more intimidating.
Incumbent: Messi is widely regarded as the current best player in the world
He is two away now, though, and getting stronger.
Logic suggests the quest must end in the Donbass Arena against Spain, that one man cannot ride the famous passing carousel and win.
Yet Spain are not Barcelona.
Ronaldo will be well aware who is missing and the point he has to prove. Sandro Rosell, president of Barcelona, said the club have an entire team with more talent than Real Madrid’s Ronaldo.
But they haven’t. They’ve got one guy who is arguably better. And he’s not here. So this is Ronaldo’s stage, Ronaldo’s time, and if he can be Portugal’s Maradona, the debate about the world’s greatest footballer will open wide again.
For frankly, without Ronaldo, Portugal would have about as much chance of winning this European Championship as Lionel Messi.
