Chile hosts Brazil in World Cup qualifying, and the Selecao coach Dunga knows what awaits.
Brazil coach Dunga is aware of the difficulties World Cup qualifying will pose as his team prepare to face Chile on Thursday.
The South American powerhouses do battle in Santiago, looking to make winning starts to qualifying in CONMEBOL.
While both are expected to advance as two of the top four that gain automatic places at Russia 2018, a loss would leave them with work to do.
Dunga has made a late change to his squad, with injured Liverpool star Philippe Coutinho replaced by Kaka.
