Rivalry has been a fixture in the international sporting calendar since the beginning of the 20th century.
It is an unspoken part of the modern sport.
And as the Argentines’ World Cup campaign begins, there is an argument to be made that it is the most important rivalries in world sports.
Argentina and Brazil are the two best-known, and in recent years, the two have been pitted against each other at the world’s biggest sporting event.
It has been the subject of many great articles, ranging from the controversial (Brazil’s World Cup winning side) to the hilarious (Argentines’ defence of their national stadium).
And the rivalry between Argentina’s star players, Lionel Messi and Andres Iniesta, has been also discussed.
The rivalry between the two sides has also been linked to other World Cup-related controversies, including the FIFA corruption investigation.
It started when Argentina won the 2010 World Cup and then took a back seat to Brazil in the final, and has now reached the next level, as the two teams are battling for a place at next summer’s World Championships.
But the rivalry could be the most interesting to follow in world football.
The two countries have not met in the last five years, and the current World Cup is the first time they have met since the 2014 World Cup.
Argentina will be hoping for a third consecutive World Cup title, while Brazil are hoping for another gold medal.
And while Messi is currently leading the team in all three categories, his star duo, Iniesta and Neymar, are not the only players to play a big part in Argentina’s success in Brazil.
Cristiano Ronaldo, who scored the most goals in the tournament, and Neyma was the most prolific scorer of the tournament.
Cristian Tello is another star, scoring 12 goals.
Both players have also become key figures in Argentina, and while the two will be vying for the ball, their respective performances in the World Cup will also be key to their future fortunes.
So, how will this rivalry play out?
The two teams will play each other four times at the World Championship in Russia next month, with each match being the first of four matches between the sides, each with a different referee.
Both of these matches are being contested by Argentina’s national side, with the Argentinian side taking on Uruguay and Uruguay taking on Argentina.
Both sides are currently competing for the title of best-ever team in the world, with Brazil coming in second, and Argentina finishing fourth.
What will be the biggest rivalry between these two teams?
Will the Argentine national team really be able to defend their title?
Neymar has scored 27 goals in his last seven games for Argentina, while Ronaldo has scored 26 goals in those games.
Neymar scored against Uruguay in Brazil in January, which gave the Argentinos a 2-0 lead.
But Uruguay dominated the first half, and Ronaldo scored twice to give the Argentinas the lead.
Argentina are now looking to keep their lead, but if they can keep their defensive discipline and win the ball back, it will be a very tough task for Uruguay.
And if Argentina can defend well and win possession well, they will be able be competitive.
The Argentinian defenders will have to stay calm and keep the ball well, and Messi will have the ball as well.
Will Neymar and Ronaldo be able control the game?
They both are technically gifted players, and have a lot of experience.
But in this World Cup, it is unlikely that Messi will be allowed to dictate the pace of the game.
He is capable of going forward, and is capable enough to score goals.
And in the early stages of the match, the Argentinians have struggled to contain Messi.
However, the Argentine midfield is still very strong, and it is very important for Argentina to control the ball and defend well.
Neymé is capable, and he has scored a lot more goals than Ronaldo.
What are the chances of this rivalry playing out?
Argentina will look to get their best players involved in their defence, and will look for the best way to win the game for them.
Ronaldo and Neymés will be involved in all areas of the field.
Messi is still the team’s star, and should have the chance to score, but there are no guarantees.
It will be important for both teams to control possession well and hold the ball.
Argentina has already won four World Cup games, but it will also look to win a third, and to try and make Brazil look like a joke.
The last World Cup Argentina played in, they lost 3-1 to Brazil.
Will Messi and Ronaldo really be playing at their best?
Both players are very gifted players.
But it will take a lot for Messi and Cristiano to be the best team in world soccer.
But if they play well, Messi and the Argentins will have a great chance to win.
