Given the intense rivalry between the 2 teams, and the legions of fans from Argentina in Brazil, I suspect there will be 'incidents' between the fans if they met in the final. Especially if Argentina claim the biggest prize in World Football on Brazilian soil.

If you're a Brazilian police officer hoping for some leave on or around the 13th, you'd be hoping for a Colombia and/or Belgium victories this weekend.

Hopefully all the action will stay on the pitch.

Oh I'm sure FIFA will find a way to make these two don't meet in the final.

I wouldn't worry. Neither team will get that far.

Trouble is there will probably be violence/protests IF/WHEN Brazil go out.

I bet its their worse nightmare to see Argentina win the World Cup...a bit like Uruguay in 1950.

If Argentina don't raise their game significantly against Belgium they're going home.

To be honest, both Brazil and Argentina have looked very ordinary in this tournament and it would be very disappointing to see either of them win it.

Would love to see a Netherlands - Germany final, the way things are going we could see a European Team win the WC in South America, with 4 Euro teams and 4 South American teams left, it's been a long time coming.

That's exactly right, for me there's been a sense that the protests before the World Cup started were put on hold basically for the duration of Brazil's involvement. Once that comes to an end, I think there'll be a ramping up from what went on before it started, and that will mean that the police will be overworked more than ever before I suspect.
