The 29-year-old World Player of the Year endured an afternoon to forget at Salvador's Arena Fonte Nova where he was over-shadowed by Thomas Mueller's hat-trick.
Ronaldo's fortunes were summed up when one of his trademark free-kicks cannoned off the German wall in the second-half leaving the Portugal captain with his head in his hands.
He stormed through the mixed zone after the game refusing to answer reporters’ questions.
"Until his free-kick, he didn't really do anything," said Germany right-back Jerome Boateng, who was marking Ronaldo.
The world's media were equally unimpressed.
"CR kept himself well hidden," judged Portuguese daily newspaper Publico, "A shadow of himself" summed up Spain's El Mundo Deportivo.
German daily Bild went with the headline: "Ron-NIL-do", failing to hide their glee after he was unsuccessful in any of his five shots on goal.
Portugal coach Paulo Bento was terse when asked about Ronaldo's condition, both physically and mentally, after the match.
"From a physical perspective, we can only say that he's doing well," said Bento after Ronaldo came into the Salvador game on the back of knee and thigh injuries.
Boateng also revealed how the Germans dealt so effectively with the Real Madrid star.
"The whole team worked together, with a player like that, he'll always beat his man, so you have to make sure the next one is there, that was the key," said the Bayern Munich defender.
Portugal have injury concerns ahead of their next match against the USA on June 22 with striker Hugo Almeida and defender Fabio Coentrao both having suffered leg injuries.
Bento will also be without centre-back Pepe, who is suspended after aiming a head-butt at Mueller in the first-half.
