Substitute Johan Manzambi scored his maiden World Cup goal with an outstanding volley in the 74th minute as Switzerland erupted late for a 4-1 win over Bosnia-Herzegovina to take control of their group.
Rubén Vargas scored in the 84th minute for the Swiss shortly after Tarik Muharemovic was sent off for a dangerous tackle, leaving Bosnia with 10 men.
Manzambi scored again in the 90th on a pass from Vargas, and captain Granit Xhaka converted from the penalty spot with the final kick of the game in stoppage time.
