Fans from Chile, Colombia, Uruguay and Mexico have come in huge numbers. They've been noisy, colourful and passionate. But if I had to give an award for the best fans in Brazil, it has to be Argentina.
Whether Argentina win on Sunday, this World Cup will always be remembered for Argentina's World Cup Anthem: Brasil decime que se siente? Brazil how does it feel?
This might be Brazil's World Cup, but Argentina are the noisy neighbours who have gatecrashed the party. Everywhere they've been their anthem has followed them, much to the annoyance of Brazilians.
The lyrics of the song roughly translate as:
Brazil how does it feel to be bossed about in your own home.
They then go on to reminisce about Argentina's win against Brazil in the 2nd round of the 1990 World Cup. Claudio Caniggia scoring a late winner after Maradona's dribble and pass set him up.
The song ends with the controversial taunt that Maradona is better than Pele! Argentinians already have a reputation in Latin America for being a bit full of themselves - this song does them no favours!
Personally this is what I want to see at a World Cup. With high ticket prices and FIFA's demands on how host countries should manage a World Cup. There's a risk that World Cups becomes bland and homogenised - each one looking and feeling the same.
You can't say this about Brazil. Argentina and other Latin American countries have brought a raucous, edgy and colourful presence to this World Cup and that's something I'm always going to remember.
