Portugal had to fight hard to beat Ghana, the opening goal was born from the penalty spot which was executed perfectly by Ronaldo. Portugal managed to end the game with a 3-2 winning score. Anyone will admit that Ronaldo played well against Ghana. He played in high spirits even though he had just parted ways with Manchester United, if the referee didn't award a penalty to Portugal, Ronaldo couldn't score in this game.
Nothing lasts forever and I am against focusing on single persons, regardless of their fame. It was not an easy game for Portugal and we see that many teams plays much better against 'giants' than we may expect (Ghana, Japan or SA, or even Canada). Seeing Portugal like they played yesterday, I do not think there is a big future for them in this World Cup. And of course Ronaldo is a good player, but you cannot be blind, he is different than he was 10 or 20 years ago, on his first World Cups (at least he scored a penalty goal, not like Lewandowski).
Next game they play with Uruguay, 4 years ago, in Sochi, Portugal lost 2:1.
