In 2006, Sanchez, who was only 17 years old, was attracted by Kolokolo, a domestic powerhouse, and was also selected for the Chilean national team. A few months later, he was attracted by Udinese Club, which was good at recruiting young talents. However, considering Sanchez's young age, the Infinite Corps arranged for him to continue exercising in South America. In Kolokolo's team, Sanchez can not only disrupt the opponent's defense on the flank, but also directly attack the goal from the front waist or even the striker position. He won the Chilean Spring League in 2006 and the Autumn League in 2007. In the summer of 2007, Chile's national youth team, with rising stars such as Sanchez, Isla, vidal and carmone, went to Canada to compete in the Under-20 World Cup and won the third place. The right winger Sanchez scored by himself, which also created many opportunities for his teammates. In the summer of the same year, Sanchez rented to the riverbed of the Argentine giants and appeared at the Monument Stadium. Sanchez is not the absolute main force in the river bed where the stars gather, not to mention that he was absent for a long time because of his left ankle injury. However, in the limited playing time, Sanchez won the recognition of fans with his strong breakthrough ability. In the derby against Boca Juniors, Sanchez tripped five people from the midfield and entered the penalty area to win a penalty for River Bed. This scene became his brightest moment in Argentina.
In the summer of 2008, after winning the autumn league championship with Riverbed, Sanchez finally got his wish and came to Friuli Stadium in Udine to fight side by side with national youth team and national team teammate Isla. In Serie A, Sanchez was praised by the media as "Cristiano Ronaldo of Chile" because of his talent on the right. Sanchez has 4 goals and 3 assists in Serie A this season, which is a weapon for the Infinite Legion to attack on the right. Manchester United and other giants have begun to pay attention to the Chilean teenager, but Udinese has also offered him at least 20 million euros. In Chile's national team, the 33 13 formation of head coach Belsa has high requirements for wingers' offensive ability. Sanchez, with strong offensive desire and outstanding personal ability, is the most suitable candidate for the right wing position. Sanchez is at home in Belsa's 33 13 formation. He contributed three goals in the preliminaries and got many assists. He is an indispensable member of the Chilean team.
Sanchez's height is only 1.7 meters, which is a little stocky, but his speed and foot frequency are extremely fast and his explosive power is amazing. He has gorgeous dribbling skills, and all kinds of tricks such as riding a bike, pulling the ball, hitting the ball with his heel and picking the ball are perfect. Very low center of gravity and steady footwork can often make him stop suddenly and leave the defender behind. Sanchez's shooting and passing skills have also improved a lot in the top leagues. Whether he is a guest striker or a front waist, he is a threat. However, on the court, Sanchez also has the same weaknesses as young players. He often sticks to the ball too much by virtue of his outstanding skills. His sense of cooperation with his teammates is still lacking, and his physical confrontation needs to be strengthened. Sanchez will be the number one attacker on Chile's right in the World Cup in South Africa. The left-backs of the teams in Group H will certainly rack their brains to guard against this super fat little man.
