Gonzalo Antonio Fierro Caniullán (born 21 March 1983) is a Chilean footballer. He currently plays as a right winger for the Chilean club Colo-Colo. Previously, he already had played for Chile's major club for almost seven seasons. In his native country he is known as "El Joven Pistolero", which means the young sniper, due to the accuracy of his shots.
Fierro began his career with Chilean giants Colo-Colo, where he received the nickname "El Joven Pistolero" (The Young Gun). In 2005, he scored eleven goals and gave numerous assists while playing with other prominent players such as Humberto Suazo, the world's top international scorer in 2007 and the Mexican League's top scorer in 2008; Matias Fernandez, who preceded Carlos Tévez as the Americas's best player in 2007; and Alexis Sánchez, who went on to play in world-renowned club River Plate and is now at Italy's premier club, Udinese Calcio. However, he still found the back of the net, scoring ten goals in 2008. In his initial years, Fierro scored a dozen goals in the Chilean League as well as two 30 meter rockets in the Copa Sudamericana 2006. He scored three more goals at the Copa Libertadores 2007 and was a regular starter at the Copa Libertadores 2008, where he scored against Unión Atlético Maracaibo, and was a key man in 2–0 win against Boca Juniors, where he took a penalty kick.
Fierro had his second chance in the first team only on 12 July 2009, this time against Brazilian Série A defending champions São Paulo in Morumbi Stadium, he was the choice to replace Ibson after the end of his loan. In this match he scored his first goal ever for Flamengo with only three minutes of playing after receiving a pass from Adriano.
Fierro played for the Chilean National Team at the Copa América 2007 against Ecuador, Brazil and Mexico. He also played for the National Team in a tour of Europe with world-renowkn coach, Marcelo Bielsa, who won the gold medal at Athens 2004, won the most points for Argentina in any qualification process for 2002 and additionally brought his experience of managing champion teams in Mexico and his homeland of Argentina. Bielsa had so much faith in Fierro's abilities that he immediately took him into his new process, nominated him to play the two hosts of Euro 2008, Austria and Switzerland, where Chile won 2–0 and lost 2–1 in a game where Chile was inexplicably denied a legitimate goal. In a tour of Asia in 2007 where Chile played the two hosts of the 2002 World Cup, Fierro played and scored against South Korea in a 1–0 win and played the 90 minutes in the tie against Japan 0–0. In the 2010 World Cup Qualifiers, Fierro started in the 0–2 loss to Argentina, the 2–0 win against Peru, the historical 2–2 tie against Uruguay in Montevideo, and the 0–3 loss against Paraguay. Due to his demanding season he stayed out in the 2–0 win against Bolivia in La Paz, and the 3–2 win against Venezuela in Caracas. Fierro then played against Euro 2008's most entertaining squad, Turkey, in a tight 1–0 loss in Istanbul and has been nominated to play Brazil as well as Colombia on 7 and 10 September of this year.
