Ronaldo didn't carry Portugal to the World Cup single-handedly, that's an hyperbole erring on the disrespect to the other (not many indeed) top Portuguese players. He carried us through the play-off with his goals (none of which was of his exclusive merit) and insane finishing ability. In the group phase he scored 4 out of 20 goals (against N. Ireland and Luxembourg) and was invisible in most of the other matches.
If the team isn't good enough overall, it won't be him alone to turn it around for us, I don't remember him ever doing that. The time he spends on the wing when we're in possession is invariably a waste, he never beats his man any more to create a goal out of nothing. In the first tie against Sweden he was dire the whole match, went to the finishing area at the end of the game, scored a goal and hit the bar a couple of minutes later.
Yesterday he had the prime conditions to succeed in the second half, with Sweden chasing a disadvantage, the space he craves so much, and pinpoint world class assists that don't happen every game either. It was more of a "Real Madrid" Ronaldo, and unanimously considered his best performance ever for the Portuguese team. It came perfect and at the right time.
We're not a one man team, and it's a shame that even the Portugues press in relentless adulation are the first to blame for this idea. We're like any other team that would be dramatically inferior if you take their best player off. To say otherwise is disrespectful to players like Meireles, Moutinho, Pepe, Alves, Coentrão, who worked their bollocks off to earn points for Portugal during the 8 qualifiers or so that Ronaldo failed to be seen at all and pouted due to receiving inferior service than what he usually gets at Real.
Not to take anything away from his sublime ability and form of course. I don't think any other player in the world, bar a Messi at the top of his form, which he isn't, could have taken those chances.
