The inexperienced duo came on as second-half substitutes and produced an impressive display with Pato scoring the decider in the 72nd minute.

"He knows how to score a goal. He is young for this sort of thing, and also because the media is always on top of him. But he's a humble, modest person, he keeps working," Dunga told Skysports.com.

The former World Cup winner also backed Anderson who was booed by the London fans.

"Because he plays with Manchester United there is some feeling there, but it is not because of the football that he played. He showed his personality. He showed that his characteristics are strong," added Dunga.
