Gilberto faces one of the biggest matches of his international career tonight when Brazil face Argentina in a crucial 2010 World Cup qualifier in Minas Gerais.
A clash between the two giants of South American football is always hotly anticipated throughout the world of football, but this encounter takes on extra importance for the Samba Boys after a disappointing start to their qualifying campaign.
A 2-0 defeat to Paraguay at the weekend means a lot more than just national pride is now at stake for Gilberto and co, and he is determined to not let his country down.
He said: "This is now a very important match. We must perform because this is the biggest match in South American football and it means so much to the people of both countries.
"Argentina are a great team with some fantastic players, but we are playing at home now so we have a big chance and we must be confident.
"Before the Paraguay game, I was hoping we would take six points from these two games and be in a good qualifying position, but now this is not possible.
"However, with a passionate Brazilian crowd fully behind us, we can hopefully get the right result against Argentina and this will give us the confidence to go on and qualify for the World Cup."
Our left-back is the first Brazilian international to have pulled on a Spurs shirt, and he informed us that the five-time World Cup winners are quietly confident going into the game despite recent poor form.
Gilberto added: "We have won our last three encounters with Argentina, including the final of last year's Copa America, so we know what we are capable of. If we can play as a team, we know we can win this match."
