Edin Dzeko bagged a brace as Bosnia-Herzegovina moved a step closer to their first major finals appearance with a 4-1 victory over Liechenstein in their penultimate World Cup qualifier.
Dzeko scored either side of goals from Zvjezdan Misimovic and Vedad Ibisevic as Bosnia struck four times in 13 first-half minutes to effectively seal the win.
The result means Safet Susic's men, who top Group G, can book their World Cup place with victory over Lithuania on Tuesday.
Bosnia made clear their intentions with Peter Jehle forced into his first save after just 90 seconds, pushing aside a shot from Haris Medunjanin and then, moments later, Dzeko's effort from the resulting corner.
It took until the 27th minute for the breakthrough to come, with Misimovic crossing from the right for Dzeko to head back across goal.
Dzeko tried to add a second almost immediately, but his powerful effort was turned away for a corner.
However, they did not need to wait long before the second came as Senad Lulic teed up Misimovic who slotted home comfortably in the 33rd minute.
Dzeko blazed over seconds later but it hardly mattered as Bosnia had their third goal by the 38th minute, Ibisevic getting up to head home Avdija Vrsajevic's cross in the 38th minute.
And they effectively killed Liechenstein off completely with another goal seconds later, with Dzeko bagging a second as he slotted home from Miralem Pjanic's pass.
Liechenstein held out without further damage before half-time and, although they continued to come under heavy pressure in the second half, Jehle denying Ibisevic, Misimovic and Haris Medunjanin in quick succession, it was the hosts who registered next as Nicolas Hasler pulled a goal back with a header from Michele Polverino's corner.
Bosnia had further chances to add to their lead - Dzeko passing up more than one opportunity to bag a hat-trick - but they had already achieved their primary objective of three precious points in the push for Brazil.
