The Freiburg midfielder bagged a double as the Swiss went on a second-half goal spree.
Switzerland 4-1 Bosnia and Herzegovina
Switzerland goals: Manzambi (71, 90) Vargas (84), Xhaka pen (90+7) Bosnia and Herzgovina goal: Mahmic (90+3)
Switzerland moved to the top of Group B after a Johan Manzambi-inspired victory over ten-man Bosnia and Herzegovina.
The Freiburg star struck twice in a goal-laden second half as the Swiss followed up their opening-match draw against Qatar with an impressive and ultimately deserved victory.
After a forgettable first period, the match burst into life after the interval when Manzambi crashed home an unstoppable first-time strike. Substitute Ruben Vargas doubled their advantage with a smart right-footed finish before setting up Manzambi to settle the outcome and put himself in the adidas Golden Boot picture.
The Bosnians, who had lost Tarik Muharemovic to a red card for a professional foul on Breel Embolo, pulled a goal back in stoppage time with a ferocious Ermin Mahmic strike. There was no hope of a comeback, though, and Switzerland captain Granit Xhaka restored their three-goal cushion as time ticked down with a coolly dispatched penalty.
