Speaking in a press conference ahead of Brazil's first World Cup game, the Chelsea centre-back reflected on the honour of being handed the armband and enjoying his best days in the twilight of his career.
"I'm enjoying the best version of Thiago Silva," he said. "At 38, I'm going through one of the best phases of my career.
"Today I'm certainly a much better person prepared for this moment, super calm and super comfortable here, with everyone's trust.
"I've always been prepared for all situations and I thank the coach for naming me captain, it's a special moment."
There are big expectations back home, from Rio de Janeiro to Sao Paulo, that Brazil can become world champions for the first time since 2002.
"I ask the fans to trust us," added Thiago Silva. "We are ready to have a great World Cup. The title is a long way off but dreaming is free and we dream about it.
"The fact we won in 2002 is a great inspiration to all of us. We have images from all the World Cups we've won and that's a source of inspiration and motivation that we can continue making history."
