I've seen several Irish supporters, obviously miffed that their team didn't qualify (lol), wearing both Argentina and German shirts since the competition started.
Good for them.
Now it's the final, who is your money on?
GERMANY
Fearless Joachim Low wants Germany to make history in the Maracana on Sunday and then dominate world football for many years to come.
After their 7-1 demolition of Brazil in the semi-final, Germany are big favourites to beat Argentina and win the World Cup in Rio.
If Germany are successful, it will be fourth time they have won the famous trophy - but it will be the only occasion they have triumphed on South American soil.
Indeed, no European nation has won the tournament on this continent in four attempts.
Czechoslovakia and Holland reached the final in 1962 and 1978 respectively, but Low hopes his team can go one better in Brazil this weekend.
Joachim Low: "In the past we never had this, so we know we can write history.
"Latin Americans, on this continent, have dominated all the time. So why can we not be the first?
"This could be considered an additional joy for us if we were to win as Europeans on Latin American soil.
"We have players right now who are playing at their peak, but we have young players also in the squad and others who aren't even here.
"We have players with a fantastic future: Gundogan, Reus, (Mesut) Ozil, Schurrle, Muller... they can go on to play for a number of years.
"We can play on top of the world for a good few years yet, with some young players coming in to reinforce the team."
ARGENTINA
Sergio Aguero thinks Argentina's underdog status will play into their hands when they face Germany in this Sunday's World Cup final in Rio de Janeiro.
While Joachim Low's side smashed hosts Brazil 7-1 in their semi-final, Argentina only managed to squeeze past the Netherlands on penalties in Sao Paulo on Wednesday, prompting the Germans to be installed as heavy favourites to win the World Cup for a fourth time.
Sergio Aguero: "Germany were always the favourite.
"They continue to be so now. We need to play our own game and it suits us that all the pressure is on them.
"We are in the final and we have to play it and win it in whatever way possible.
"We want to have control of the ball, but we know that Germany is a great team that know each other off by heart having played together for many years.
"It is clear that Argentina always go out to win, but sometimes during the game you have to be cautious. We are all aware of what the objective is and we will leave everything on the field to achieve it."
