Nations Cups, as well as at the 2007, 2009 and 2011 CONCACAF Gold Cups. On 22 June 2008, Eliseo scored two goals as El Salvador came back in a thriller to defeat Panama, 3–1. With the win, El Salvador advanced to Round 3 in the CONCACAF Zone in the World Cup Qualifiers for Africa 2010. On 28 March 2009, Quintanilla scored his twelfth, and quite possibly most memorable goal with the national team. The goal came in a World Cup qualification match against the USA and marked the first time in over eleven years that El Salvador had managed to score a goal against them. The match ultimately ended in a 2 all draw.
