If Arsenal fans did not know much about Alexis Sanchez during his Barcelona days they will have learned a great deal about him throughout the World Cup because, not only was he the star who carried an exciting Chile team through to the knockout stage of the competition, but it appeared as though Arsene Wenger had genuine interest in the player.
That interest was a two-way thing as Sanchez rejected overtures from Juventus and Liverpool to sign a four-year contract at the Emirates Stadium and the forward, who was responsible for two goals and one assist from four appearances in the competition, has indicated that, even at his age - 25 - he remains a student of the sport and learned a great deal from the experience.
"Sadly Chile couldn't progress any further but we gave our best and we showed that we are a strong team with quality," he said. "I feel we earned everyone's respect.
"On a personal level the World Cup changed my life completely. I learned attacking and defensive concepts and my decision-making on the pitch improved a lot too."
On who he most looked up to when he began competing, Sanchez explained that his compatriots Ivan Zamorano (Real Madrid and Internazionale) and Marcelo Salas (Lazio and Juventus) both hold a special place in his heart as "they were important Chilean players."
But stressed that the biggest influence on his playing career would be his idol Ronaldo, of Brazil: "I always admired him as a player. He was very strong on the pitch and watching him really motivated me to play football."
Concluding, the player - who returned 19 goals and ten assists last term - said: "Ultimately I have come to Arsenal to win everything possible thing with the help of my team-mates.
"I look forward to making the fans very happy!"
