Against Switzerland, Chile lost 2–1 but had a legitimate goal called off and Austria, where Chile comfortably won 2–0.

After two great performances Estrada was called up for two friendlies in Asia against Japan, where Chile held the hosts to a 0–0 draw and South Korea, where Chile won 1–0.

Both matches were played in tough scenarios in the 3600 meter altitude Hernando Siles Stadium in La Paz and the Copa America 2007 Puerto Ordaz Stadium in Venezuela. Chile surprisingly won both games 2–0 and 3–2. Estrada proved to be extremely consistent in both matches, playing as a left wing back and a centre back and went on to be a regular in the Chilean national team during three years. Estrada scored his first International goal on Wednesday 10 June. when his curling free kick beat Bolivian goalkeeper Carlo Arias after midfielder Ignacio Garcia of Bolivia was sent off in the 71st minute. Estrada replaced the suspended Carlos Carmona in the starting line up Chile's final Group H match at the 2010 FIFA World Cup, but was sent off with a second booking at 37 minutes following a dive by Fernando Torres in the lead up to their opponent's Spain's second goal in a 2–1 win.
