Here he refuses to celebrate the goal: "Never forget that..."

Switzerland had the best possible start to the World Cup, when they beat Cameroon in the opener.

25-year-old Breel Embolo was the match winner.

He scored the only goal of the match - but there was no celebration.

The reason is that the striker was born in Cameroon.

- When I chose Switzerland, a part of me wanted to represent the country of my birth.

I am Cameroon's biggest fan.

I never forget where I came from, he said before the match.

Switzerland and Cameroon play in the same group as Brazil and Serbia.
