And if Portugal doesn't go through the Group Stage? Cautious or Realistic?

I was reading the EurOpinião blog. This post stopped me in my tracks:

E se Portugal não passar da fase de grupos?

(And if Portugal doesn't pass the group stage?)

Dois dos treinadores mais conceituados do Mundo pronunciaram-se sobre a possibilidade de Portugal não passar à próxima fase do Euro2008. Luiz Felipe Scolari, que já afirmou há poucos dias querer a Taça, confessa que a eliminação precoce de Portugal seria horrível. José Mourinho fala dessa hipótese qualificando-a de ridícula. E qual é a sua opinião?

(2 of the most known managers in the world have had their say about the possibility of Portugal not going through to the next stage of the Euro 2008. Scolari, that a few days ago said he wanted to win, confessed that the early elimination of Portugal would be horrible. Mourinho says that not going through the group stage is 'ridiculous.')

It's ok to be cautious. But Portugal has just played the 1st match. A victory, scored 2 goals. I think Portugal can go through the group stage. Even as a runner-up. One of the comments on that post shows how one reader is too cautious or realistic:

"Portugal won't qualify for the next stage because it will lose against Czech Republic and draw with Switzerland, which would make me very sad. On the other hand, it would be accurate because of the lack of humility of some players and also because of the excessive euphoria of portuguese. Won a game and it looks like we were champions."

- Do you think Portugal has the necessary game, forwards, to go through the group stage?
