Brazil coach Dunga has handed a first senior call-up to Internacional midfielder Sandro for the World Cup qualifiers against Argentina and Chile.
The 20-year-old, who captained the Brazil Under-20 side to the South American title in Venezuela earlier this year, takes the place of Wolfsburg captain Josue who was ruled out after undergoing knee surgery.

Brazil lead the South American World Cup qualifying group with 27 points, one point better off than Chile, three ahead of Paraguay, and five clear of Argentina.
