How they qualified: For the second time in successive qualifying campaigns, Portugal did it the hard way via the play-offs. Cristiano Ronaldo, who else, scored all four goals as the Portuguese beat Zlatan's Sweden 4-2 over two thrilling legs.
World Cup pedigree: Portugal didn't play in a World Cup finals until 1966 but they (Eusebio above all) made their mark on that tournament, losing to hosts England in the semi-finals. It took them another 20 years to qualify for the main event, but they didn't get out of their group at Mexico '86, then missed out on all three finals in the Nineties. They made it to the last four for the second time in 2006, going down against France, and in 2010 Ronaldo and co. were edged out by winners Spain in the Round of 16.
Main man: Cristiano Ronaldo, naturally. This season he's reached a new level of virtuoso brilliance, winning matches for Real Madrid and Portugal almost at will. On recent form, he's certainly the best player in the world – only the most hardcore of Lionel Messi fans could argue with that.
One to watch: Monaco star Joao Moutinho is a magnetic presence in midfield, and he is Portugal's second-most influential player behind you-know-who. Moutinho's precision passing is a joy to watch, and his reading of the game is up there with the very best.
What are their chances? A one-man team is a fallacy in football these days. But tell that to Argentina fans who watched Diego Maradona in 1986. Ronaldo is good enough to lead his team deep into the tournament, but the relative lack of quality of most of his team-mates will surely tell in the end – and Group G is no picnic.
