Breel Embolo scored against the country of his birth as Switzerland defeated Cameroon 1-0 to make a winning start to their World Cup campaign on Thursday.
Embolo struck three minutes into the second half at Al Janoub Stadium as Switzerland secured a vital three points in a group that includes tournament favourites Brazil and Serbia.
Cameroon have now lost their last eight World Cup matches going back to 2002.
Roger Milla was presented with an award before kick-off as the oldest goalscorer in World Cup history, a reminder of past glories for Cameroon who have won just one game since reaching the quarter-finals 32 years ago.
Cameroon coach Rigobert Song, who played at four World Cups including with a 42-year-old Milla in 1994, opted for the in-form Eric Maxim Choupo-Moting to lead the attack in place of usual captain Vincent Aboubakar.
African teams had made an encouraging start in Qatar after all five failed to get past the group stage in 2018, but Cameroon will regret not making more of a first half they controlled.
