Klinsmann's side finished as surprise Group A winners on goal difference ahead of Colombia, against whom they lost 2-0 in their opening match before bouncing back to beat Costa Rica 4-0 and Paraguay 1-0. The Stars and Stripes can count on the raucous support of the majority of fans at Seattle Sounders' CenturyLink Field against Ecuador, who drew 0-0 and 2-2 against Brazil and Peru respectively before thrashing Haiti 4-0 to finish second in Group B. At the 2014 World Cup finals in Rio, Klinsmann watched his side extend Belgium before bowing out 2-1 after extra time in the first knock-out stage and the German wants his players to adopt a different mindset against Ecuador. USA beat Ecuador 1-0 in a warm-up friendly in Frisco, Texas at the end of last month thanks to Darlington Nagbe's 90th-minute volley and will attain Klinsmann's pre-tournament target of reaching the semi-finals with victory.
