Alexis Alejandro Sánchez Sánchez (IPA: [aˈleksis ˈsantʃes]; born 19 December 1988), is a Chilean footballer who plays as a forward for FC Barcelona and for the Chilean national team. He is well known for his excellent dribbling ability, great speed, his unusual strength for a fast winger.
Sánchez began his career as a youth player for Cobreloa in 2003, aged 15, for then be promoted to the first adult team, two years later. His precocious talent caught the attention of Udinese, team of the Italian Serie A, and signed the 17-year-old for US$3million in May 2006, but was immediately loaned out to Colo-Colo, and then River Plate where he was able to mature in less physically demanding confines than the Italian first division.
He joined Udinese after becoming champion of the Argentina and Chilean leagues in June 2008. Sánchez made a steady progress in his first two seasons at Udinese, and in the 2010-11 season he established himself as one of the key player's that allowed Udinese to finish fourth in Serie A. On 27 February 2011, Sánchez scored four of seven goals as his team defeated Palermo 7-0, playing only the first 52 minutes of the game. This event meant he broke the record of goals scored by a Chilean player (in a single match) in the Italian Serie A, thus beating the records set by his historic countrymen Marcelo Salas and Ivan Zamorano.
Sánchez made his international debut for his national team against New Zealand in April 2006, becoming the youngest player ever playing for the national team with only 17 years and 4 months, and scored his first goal against Switzerland in a 2–1 loss, being also the first goal of the Marcelo Bielsa era. During the Bielsa period, he was Chile's top scorer with 12 goals, surpassing Humberto Suazo's previous record of 11 goals.
