CHICAGO – The U.S. women’s national team will open its 2018 schedule against 2017 UEFA Women’s Euro runners-up Denmark at San Diego County Credit Union Stadium (formerly Qualcomm Stadium) Sunday, Jan. 21 at 7:30 p.m. ET (ESPN).

The Americans played an ambitious schedule this year, facing seven of the other top-nine teams in the world.

Denmark advanced to the UEFA Women’s Euro final before falling 4-2 to the Netherlands. The Danes defeated Belgium, Norway, Germany and Austria (in penalty kicks) before falling to the Dutch (after also losing 1-0 to the eventual champions in group play).

The U.S. has played Denmark 24 times, but this will be the first meeting since March 2014 at the Algarve Cup in Portugal, a 5-3 loss for the Americans. That result set the record for most goals allowed by the U.S. women in a match.

The Americans will travel to San Diego for the match at the end of its annual January training camp in Carson, Calif.

Tickets go on sale to the public Friday, Dec. 1, at 1 p.m. ET PT through ussoccer.com and by phone at 1-800-745-3000. Groups of 20 or more can order directly at ussoccer.com. Note: Tickets will not be sold at SDCCU Stadium except on the day of the event.
