New boys

Iceland and Panama are the two World Cup newcomers so far.

Iceland is beloved worldwide after its run to the 2016 European Championship quarterfinals and will be the smallest nation by population — only 330,000 — ever to play at a World Cup. Expect the country’s trademark thunderclap salute between players and fans to be admired and copied across the tournament.

Panama’s unlikely 2-1 win Tuesday over already-qualified Costa Rica relied on a “goal” that never crossed the line, and an 88th-minute strike from Roman Torres.
