The Bosnia-Herzegovina and Roma star says his side possess the quality to challenge anyone on the biggest stage as they prepare for their World Cup opener on Sunday
Safet Susic's side go up against the South American giants in their opening match of Group F at the nation's first ever World Cup.
And despite the prospect of facing the likes of Lionel Messi and Sergio Aguero, playmaker Pjanic is confident that his country can give Argentina a run for their money.
"We will be against one of the favourites in Argentina, but we have the expertise to challenge them," he told Sky Sport 24 .
"We do not fear anyone because we believe in our chances.
"Many of us have played in big European tournaments and know how to deal with certain situations.
"Progressing from the group is our goal. Brazil is beautiful, we are realising how fascinating this country is."
Bosnia-Herzegovina will be making their first ever World Cup finals appearance and follow up their Group F opener with Argentina with matches against Nigeria and Iran.
