Substitute Johan Manzambi delivered a decisive impact off the bench, netting twice in a breathless final 20 minutes as Switzerland swept aside Bosnia-Herzegovina 4-1 to move firmly within reach of the World Cup round of 32.

Switzerland were in control for much of the contest, but it was Manzambi's brace late in the match that put the result beyond any doubt and lifted the Swiss firmly into contention for a knockout-stage berth.

The victory pushes Switzerland to the brink of the round of 32, a significant step for a side that has arrived at this tournament with genuine ambitions of a deep run.

Manzambi's intervention from the bench underlined the value of squad depth at a tournament where games can shift in an instant. Coming on as a substitute, he seized his moment with the composure of a player entirely at ease on the biggest stage.

Bosnia-Herzegovina, for their part, made things competitive for long stretches but ultimately could not cope with Switzerland's quality and intensity across 90 minutes. Their consolation goal offered little comfort as the Swiss ran out comfortable winners in the end.

Switzerland now turn their attention to securing a confirmed place in the round of 32, knowing that a performance of this calibre will give coach and squad significant confidence heading into what could be decisive fixtures.
