The Chelsea midfielder is allowing himself to think about the prospect of winning the tournament at home this summer.
Ramires has won the FA Cup, Europa and Champions League titles at the west London club, in addition to domestic honours with Benfica and Cruzeiro as well.
But the Brazilian international told GloboEsporte.com that becoming a world champion in South America would be the moment he would set above all others.
He said: “It’s a story of a lifetime, isn’t it? Only to play in a World Cup. If you win in your country, it is a story of a lifetime.”
