The U.S., brimming with confidence after topping their group, enters the knockout round as favorites against Bosnia-Herzegovina. But history is against them, having never beaten a European side in the World Cup knockouts before.While the Americans made it to the semifinals at the inaugural tournament in 1930 by winning their group, their only win in a knockout round came in 2002 when they beat rival Mexico 2-0 before losing to Germany in the quarterfinals.The U.S. is 1-13-7 against European teams since 1990, with the only win coming in 2002 in the group stage opener against Portugal. The Americans are winless in their last 13 matches against European squads at the tournament since then.Ranked 61st, Bosnia lacks the pedigree of many of those past European opponents and only managed a solitary win in the group stages against soccer minnows Qatar.
