The coach believes that retaining la Roja's style is vital if they are to triumph over a strong Selecao side, who he sees as posing threats aside from Neymar
The hosts have won every single game en route to the showpiece Maracana match while la Roja are yet to concede a goal in open play and are looking to lift the only major international trophy they are yet to win.
Del Bosque is aware of the threat that the Selecao pose but asserted that his side would seek to ignore pressure, play their own game and rely on the quality within the team.
"We will play with courage, bravery and without fear - with respect for our own identity and our style of play," Del Bosque told AS.
"We have to bear in mind the team who we will be playing against but not alter our own game to suit them. At this stage, we cannot afford to mess around or lose our identity.
"Every day we have more responsibility. We really noticed it after winning Euro 2008 and it increased after the World Cup. However, the players retain that determination to continue winning after all the battles they have been through.
"To keep realising your dreams is a positive way to go through life’s journey and that is exactly the quality which my players have - once they realise one dream, they set their hearts on another."
However, whilst the Spaniard will refuse to alter his tactics, the ex-Real Madrid trainer is aware of the dangers within the Brazil line-up.
"Brazil are much more than just Neymar," Del Bosque continued. "They are a brilliant team who have two of the best full-backs in the world - [Dani] Alves and Marcelo - and their two centre-backs [Dante and Thiago Silva] are amongst the world’s best.
"They have other players like Paulinho and Oscar who are capable of resolving a game if their strikers, Fred and Hulk, haven’t already done so.
"We will be extra careful with their aerial play, that’s an area in which we must be particularly vigilant."
