The Chilean moved to Barcelona in July 2011 from Udinese for £23m and was expected to immediately flourish in Spain after three good seasons in Italy.
But the 25-year-old failed to meet the high expectations of the Barcelona fans during his first two years at the club, and came under plenty of criticism last season.
Just this time last year, it was thought Sanchez would be moving on. But he has developed his game and is now a key part of an attacking Barcelona side.
Sanchez can play anywhere across attack, but is most effective on the right-wing. He scored 20 goals in 54 appearances in the league during his first two seasons at Camp Nou.
He is now a regular in the side under Gerardo Martino and has started 18 times in his 20 league appearance this campaign.
Sanchez is Barcelona’s top-scorer in Liga BBVA with 15 goals, two more than Lionel Messi who has missed a chunk of the season through injury.
The Chilean has also created 28 chances for his teammates, with six assists for the season up to this point and is an integral part of the team.
He netted his first Barcelona hat-trick last month in the 4-0 win over Elche CF and seems to be improving every week.
Sanchez’s international form has been just as impressive, with seven goals in his last seven games for Chile.
He was the best player on the pitch at Wembley when Chile faced England in November, and he grabbed both goals in the 2-0 win on that occasion.
Sanchez has 64 international caps and is the star man in an exciting Chile side that are dark horses for the World Cup in the summer.
Alexis Sanchez will look to take his remarkable form into the World Cup where Chile open up against Australia on June 13.
A player who Manchester City tried to sign themselves ahead of his switch to La Liga, he is perfectly poised to show the Premier League side exactly what they are missing.
