Futsal legend Falcao has hung up his boots at the age of 39.
The Brazilian star bowed out after Brazil were eliminated by Iran at the Fifa Futsal World Cup Colombia 2016.
A teary-eyed Falcao, who scored a hat-trick against the Asian champions on Wednesday, said: "I remain very happy having finished my career with a hat-trick but unfortunately they are worth nothing.
“These goals are of no real value; they are just helping me to improve my record.
"If I was able to change everything I did in this tournament, including the goals, and be able to trade it to become world champion, I would in an instant.”
According to UK sports media outlet, The Sun, Falcao was named Best Futsal Player in the World a record four times and won the Golden Ball twice in the 2004 and 2008 World Cups.
Brazilian superstar Falcao is considered the greatest futsal player of all time.
Brazil legend Ronaldinho recently quit Indian Futsal League after just two games.
Despite failing to help Brazil win a sixth World Cup, Falcao admitted he was proud of what he had achieved in his career.
