The USMNT hadn't lost a World Cup Qualifying match since 1957. With today's loss, the Stars & Stripes are dead-last in CONCACAF's Qualifiers.

It seems like Jürgen Klinsmann's credit as USMNT's coach has ended, as fans are demanding him to face the ax after a 4-0 defeat against Costa Rica.

A brace by Arsenal's Joel Campbell and two more goals by Johan Venegas and Christian Bolaños created chaos in defense for the U.S., a team that showed no clue of how to stop Los Ticos' attacking midfielders and strikers.

This is the first time since 2001 in which the USMNT has lost two straight games in a final round of the CONCACAF World Cup Qualifiers. In fact, the last time the Stars and Stripes lost 4-0 in a WCQ came back in 1957, when they lost against Mexico.

It seems like Klinsmann will face heavy pressure in months to come, considering his team's sloppy start. Have a look at what fans and experts had to say about tonight's blowout.
