Portugal beat Brazil 2-0 in a friendly on Tuesday, ending Dunga’s unbeaten streak as manager of the South American side.
Simao Sabrosa, one of five second-half substitutes for Portugal, and Ricardo Carvalho scored in the last eight minutes to give Dunga his first loss in six games.
Both goals came from right-wing crosses.
Brazil also used the second half at the Emirates Stadium in north London to experiment with a handful of substitutes, resulting in some disjointed attacking play.
Brazil had the best chances before then, with Adriano making his first appearance for his country since last year’s World Cup, but often strayed offside or failed to make the final pass.
Dunga, a World Cup-winning midfielder for Brazil in 1994, had been unbeaten since taking over after Brazil’s disappointing quarterfinal exit to France at last year’s World Cup.
Portugal coach Luiz Felipe Scolari is now unbeaten in two matches against his native Brazil, which he led to a record fifth World Cup title in 2002. — Sapa-AP
