Star man: Cristiano Ronaldo (Real Madrid)
One to watch: Luis Neto (Zenit St Petersburg)
Coach: Paulo Bento (above)
Qualified: Europe play-off winners
Best World Cup: Third (1966)
Predicted group finish: 2
In Cristiano Ronaldo they boast a player who can turn even the biggest of games on its head, so their hopes largely rest on his fitness and form. For all the talk of depth in the squad, if he plays well, then Portugal can go far: if he struggles for form or fitness, then they are unlikely to make an in impact against the best sides.
Star man: Clint Dempsey (Seattle Sounders)
One to watch: Julian Green (Bayern Munich)
Coach: Juergen Klinsmann (above)
Qualified: First, Concacaf
Best World Cup: Semi-finals (1930)
Predicted group finish: 3
The omission of Landon Donovan from Juergen Klinsmann's squad raised a lot of eyebrows.With 57 international goals, he is his country's top scorer and no one in the squad can match his big-game experience. But he does not quite have the turn of pace he once had, and it may be time for the next generation to make their mark.
