Eren Derdiyok and Stephan Lichtsteiner netted as Switzerland maintained their 100 per cent start to World Cup qualifying courtesy of a 2-0 victory over the Faroe Islands.

Galatasaray striker Derdiyok smartly took down a long ball over the top before drilling a left-footed effort low under Faroes goalkeeper Gunnar Nielsen in the 27th minute.

And Juventus defender Lichtsteiner made sure of the points with seven minutes remaining, heading in Ricardo Rodriguez's cross from close range.

The victory, their fourth from as many games, strengthened Switzerland's position at the top of Group B.
