Brazil is the winningest team in World Cup history, and most Iranian footballers and fans love Brazil's football players and their Samba football.
Despite reaching the World Cup in 1978, 1998 and 2006, the Iranians have never had the chance to test themselves against the Selecao.
That dream has finally come true, and Iran plays Brazil's Canarinho in a friendly on Thursday in Abu Dhabi, capital of the United Arab Emirates, dpa reported.
"The whole Iranian nation is happy that Iran is playing with one of the greatest teams in the world and against the world's most renowned players," Iranian head coach Afshin Qotbi said in a press conference.
"We would have no chance against Brazil if our players did not play the game of their lives and make all Iranians proud."
Iran's skipper, Javad Nekounam, is overwhelmed with the opportunity to play against the five-time world champions.
"Since I was a little boy, Brazil has been my favourite team and playing them my dream. I thank God that my dream has finally come true," said Nekounam, who plays for the Spanish first-division team CA Osasuna.
Officials from the Iranian Football Federation (FFI) say that the game is behind held in the UAE due the contract signed between the two sides. The FFI claimed that Iran paid no money to the Brazilians for the game.
Due to political problems and especially because of Iranian President Mahmoud Ahmadinejad's controversial remarks about Israel and the Holocaust, the FFI has had problems in the last five years finding suitable national teams willing to play friendlies against Iran.
Iran have so far had only one friendly game against a world champion: Germany in 2004 in Tehran. The German team had reportedly promised Iran the friendly in return for its vote for Germany to host of the 2006 World Cup.
Observers have attributed the first-ever meeting between the Brazilian and Iranian teams to the friendly ties between the presidents of the two countries.
Brazilian President Luiz Inacio Lula da Silva is one of the few foreign heads of state supporting Iran's disputed nuclear programmes. Brazil even voted against the latest United Nations Security Council sanction resolution against Tehran.
The Iranian side, which came to the UAE from Jordan, where they finished second to Kuwait in the West Asian Football Federation Championship, is preparing itself for the Asian Championship in January 2011 in Qatar.
