Kai Havertz scored two goals as Germany overcame a brief scare from World Cup debutants Curacao before cruising to an emphatic 7-1 win in their group E opener in Houston.
Livano Comenencia levelled the game 1-1 with a left-footed strike in the 21st minute to give Curacao their first goal in the tournament and send fans of the tiny Caribbean nation into a frenzy.
But it was all Germany after that with the four-time champions regaining the lead on Nico Schlotterbeck's header off Nathaniel Brown's corner kick in the 38th minute.
The margin of victory comes well short of the World Cup record of nine goals, which has happened three times, the last coming when Hungary saw off El Salvador 10-1 in 1982.
