Portugal are one of the under-achievers of international football of recent years -though they almost rectified this in 2004 when losing in the final to under-dogs Greece.
Manager Luiz Felipe Scolari, who looks bound for the Premiership after this, hopes that his team can recapture the form that took them to the semi fianls of the last world cup. They are favourites for their group and those opening matches should provide them with some good match practice.
All eyes will be on Cristiano Ronaldo as speculation rises about a possible move to Spain, also watch out for Daniel Alves and Deco if fit.
Should Portugal ive up to their billing they could win the tournament outright, as their is no obvious powerhouse in Europe at present.

One of the star teams of Euro 2004, losing in the semis to eventual winners Greece on the silver goal rule -after having all the chances. Certain not to concede many with Chelsea keeper Cech between the sticks, but are missing Arsenal's Rossicky (injury) and Neved (retirement) -so will be reliant upon the guile of Baros and the presence of Jan Koller.
Should breeze past Turkey into the next phase to set up a grudge match with Croatia.
