I agree that avoiding a team like Brazil early in the tornament is always a good thing. BUT, if there are two teams who managed to qualify (which is the primary thing for any coach) they will play the third game more relaxed even if its a decider for first and second. MORE RELAXED does not mean play it as a friendly game, but you will notice that the player-to-player physical battle would be less. The desire to win will be there nonetheless.
It will be a different story if for an example Italy won against USA and Czech lost or drew against Ghana. Czech will play for qualification against italy which is totally different ball game than playing for leading a group.
Besides, Brazil should really think about avoiding a team like czech

.. They really tough and a very balanced team in all their lines.
