What odds are Portugal to win the World Cup?
22/1
Who's the coach?
Fernando Santos took Greece to the round of 16 in 2014 and won the Euros with Portugal at the first attempt.
Who's the star?
Old Narcissus, the often histrionic taskmaster, mardy-faced serial goalscorer and collector of Ballons d’Or, Cristiano Ronaldo.
Best thing about them
Cristiano Ronaldo’s irrepressibly prolific form and Bernardo Silva evolving into a formidably impish playmaker.
Worst thing about them
Centre-backs Bruno Alves, Pepe and Jose Fonte are 36, 35 and 34 respectively and equipped with flagging legs that require hourly ice-baths.
You may recognise…
‘Himself’, though not if your main reference points are the many sculptures of him that resemble EastEnders’ Dean Gaffney.
Cameramen will be picking out…
Anyone temporarily involved romantically with the man in the No7 shirt plus Colin Hunt types in patriotic fright wigs.
Fans' favourite chant
[Clap, clap, clap-clap-clap] Ole Ronaldo, Ole.
