His play in the tournament included two penalty saves in penalty kicks against Uruguay in the semi-finals, which sent Brazil to the final. Brazil won the tournament with a 3–0 win over Argentina. On 11 May 2010, it was announced that Doni would be part of the Brazilian squad which would compete at the World Cup in South Africa.
