Breel Embolo fired Switzerland to a 1-0 win over Cameroon in the opening World Cup Group G fixture on Thursday.
Embolo’s close-range finish put Switzerland ahead in the 48th minute, with the Cameroon-born Monaco striker opening not to celebrate the goal at the Al Janoub Stadium in Doha.
It was Cameroon’s eighth successive defeat at the World Cup, leaving them without a win in the event since 2002.
Tournament favourites Brazil open their Group G campaign against Serbia later on Thursday.
