Lucio has been watching Oscar's progress with Chelsea over the past 12 months.
"It makes the games really hard and gives great credibility to those players, a great experience. I think being used to playing at that level is very important for a World Cup.
"Chelsea is a great team and for me Oscar is the player who can make the difference in a match. He’s a very offensive player; fast, creative, skilful. He can make a difference for Brazil."
