My job when Brazil won the 2002 World Cup was to be invisible on the pitch - if I did it right, it made things easier for the players in front of me, as well as for myself.
It is the same situation now for Casemiro, the defensive midfielder who is at the heart of this Brazil team trying to end our 20-year wait to win it again. He has a great responsibility in my old position. Just as in 2002, we have plenty of attackers to make the difference this time - not just Neymar, who will miss the rest of the group stage with injury.
I can understand why some people just talk about that part of our team but, to win a World Cup, you have to remember the other parts too. Whoever the manager chooses to play further forward now, it is still important for us to be defensively strong.
Right now, I think we have the right balance. I am very happy with our back four and also with the players in front of them who teach the side to be solid. This is where Casemiro's intelligence holds the key...
