It really depends because they had not much time to prepare for this WC like any other team but if your main concern is about wearing a armband, you lose sight of the main goal.
African countries don't give shit about that, same in Asia, they just focus on the games. Look at France, despite the insistance of the media, the players said they will let politics for others and focus on the games and they won.
Germany wanted to make a statement, they must have spent time talking about what to do instead of talking about the game, preparing for it.
Don't underestimate the usefulness of a good preparation
