Seattle will play host to three Copa America Centenario matches, including one of top-seeded Argentina's group stage encounters and a quarterfinal that could potentially include the United States. CONCACAF and CONMEBOL announced the tournament's four seeded teams, the sites for those teams' group stage matches and the hosts of each of the knockout stage matches on Thursday.

The full schedule of matches will not be known until the draw is conducted in early 2016, with each of the remaining 12 countries being seeded according to FIFA ranking.

There had been rumors that Seattle would play host to the United States' opening match, which was also expected to be the tournament's opener. Instead, the USMNT will open at Santa Clara's Levi's Stadium. The United States will also play group stage matches at Chicago's Soldier Field (June 7) and Philadelphia's Lincoln Financial Field (June 11). If they manage to win their group -- which will be no easy task as it could include countries like Colombia, Chile or Uruguay -- the USMNT would play their quarterfinal match against the runners-up of Group B in Seattle. Brazil is the seeded teamin Group B. Houston and Chicago will host semifinals and the final will be at New Jersey's MetLife Stadium.

While a USMNT match may not come to fruition, Seattle soccer fans will get what might be an even bigger attraction: Lionel Messi-led Argentina. La Albiceleste are currently the top-ranked team in CONMEBOL and No. 2 in the world. They were also the runners-up in the 2014 World Cup and 2015 Copa America. In addition to Messi, they feature such international stars as Gonzalo Higuain, Angel Di Maria, Sergio Aguero and Carlos Tevez.
