It has been confirmed since Germany's mauling of Brazil that Shkodran Mustafi is the only injured absentee for the final.
That is likely to mean an unchanged team for Jogi Löw's men.
The only real question mark is over Miroslav Klose, who has been in and out of the starting lineup all tournament, but the goalscoring threat he carries - and the rampant start Germany made against Brazil - is likely to mean he plays from the off here.
Philipp Lahm will remain at right-back while the impressive Sami Khedira will start in midfield again.
Argentina will be hoping to have Ángel Di María back for the World Cup Final after a thigh injury meant he missed the semi final against the Netherlands.
Sergio Agüero came off the bench to play the final part of that match but he looked distinctly off the pace and struggled to impact on the game.
There is little chance that he will be fit and ready to start the final, and is only really likely to have an impact from the bench.
Otherwise, it could be as-you-were for the Argentines.
The 2014 World Cup Final is here, and two of the top-4 pre-tournament favourites will face off at the Estadio do Maracana on Sunday night. Germany and Argentina have both enjoyed fine runs to the final and have been the best two teams all in all.
Germany's wobble in the group stages has swiftly been overcome, and a 7-1 thrashing of Brazil in the semi-final will have quelled any nerves they might have had ahead of the final. They will be extremely high on confidence and, though their possession-based game has had its critics, they will look to control the game from the off.
Argentina had a far less convincing last match, in which they stumbled and spluttered to a nerve-wracking penalty shootout victory over the Dutch. Without Ángel Di María, they struggled for fluency and had one less creative player to take some of the focus off Lionel Messi. Even if he isn't at full fitness the Real Madrid midfielder is very likely to start and that will give Germany something else to think about.
While Argentina have plenty of players capable of producing a moment of magic - Messi, Di María, Gonzalo Higuaín have all done so at this tournament - Germany are better as a collective unit and will deservedly be pre-game favourites to lift the trophy.
The likes of Toni Kroos, Sami Khedira, Mesut Özil and Thomas Müller will provide cutting edge and perfect passing from midfield, and though this Argentine side have had a good defensive record for much of this tournament, they have been undone on occasion and a Germany side who have just put 7 past the hosts will expect to find a way through.
Argentina do, though, have the motivation of trying to win the World Cup on their fierce rivals' home soil and that could certainly spur them on.
It is likely to be a cagier affair than Germany's semi-final, but they have a fantastic chance to win here and should become the first ever European side to become world champions on South American soil.
