Here's a short story:

(CNN) -- As World Cup openers go, this was about as bad as it gets for Portugal. 

Thumped 4-0 by Germany, one key defender sent off, another possibly out of the tournament with injury and its World Player of the Year looking decidedly unfit. 

Real Madrid star Cristiano Ronaldo wasn't lacking in effort but was as powerless as those around him to prevent Portugal being steamrollered by Der Mannschaft in Salvador. 

It started badly for Paulo Bento's men and got steadily worse as Germany maintained its record of scoring at least four goals in every opening World Cup match since 2002.

They were 1-0 down after 10 minutes when Joao Pereira was adjudged to have hauled down Mario Gotze. Fellow Bayern Munich star Thomas Muller confidently slotted home the penalty. 

It was 2-0 when Mats Hummels thumped a header into the net from Toni Kroos' corner. 

Just five minutes later, Real Madrid defender Pepe tangled with Muller, who sank theatrically to the turf claiming a hand to the face. 

Pepe then stood over his opponent and pushed his head towards Muller's, the referee producing a straight red card. 

Muller then struck just before the interval to put the game well beyond Portugal, pouncing on a loose ball inside the area to fire past Rui Patricio. 

Portugal made a change at the break, as Ricardo Costa replaced Miguel Veloso, but it made little difference as Germany continued to press home their advantage. 

Mesut Ozil, who plays for Arsenal, should have found the net when played through on goal but he hit his shot straight at Patricio.  (End of story)
