HOUSTON, United States (AFP)—Four-time winners Germany thrashed World Cup debutants Curacao 7-1 in their first group game on Sunday. Kai Havertz got two goals and Nico Schlotterbeck, Jamal Musiala, Nathaniel Brown and Deniz Undav also scored in Houston to secure Germany's first opening-match win at a World Cup since their successful 2014 campaign in Brazil, after Livano Comenencia had briefly cancelled out Felix Nmecha's opener.
