The football fiesta has turned into a global party with World Cup events organized in virtually every country. One Bangladesh farmer made a 3.5km (2.2 mile) long German flag which is surrounding a stadium in the western Bangladesh town of Magura.
Germany start as favourites to win the trophy and become the first European side to win a World Cup in the Americas.
A victory for Argentina would give their captain Messi his first World Cup and elevate the four-time world footballer of the year among the game's greats such as fellow Argentine Diego Maradona and Brazil's Pele.
"Tomorrow, we will play the most important match of our lives for our country," Messi wrote in a message on his official Facebook page late Saturday.
"My dreams and my hopes are being fulfilled due to the hard work and sacrifice of a team that has given everything from match one.
"We knew it was possible. Our people, the Argentines, they have carried us here. But the dream is not over yet. Tomorrow we want to win, and we are ready!"
Argentina's coach Alejandro Sabella said the South Americans will have to produce a perfect game to overcome the talented Germans.
"Germany are always very strong physically and tactically. For that reason they are the team that has won most titles along with Brazil and Italy.
"They use the ball very well and play the ball between the lines. They also use the space behind full-backs very well, especially with (Philipp) Lahm. We have to play a perfect match."
Germany coach Joachim Loew believes his team is ready to claim a place in history as they attempt to end a run of four major tournaments where they have reached either the semi-finals or the final only to fall short.
"Regardless of what has happened in the past, it is a matter of winning now and we know we can write history, because Latin American sides have been able to dominate on home soil," said Loew.

Coach Luiz Felipe Scolari said he was leaving his fate up to the Brazilian federation.
