Roberto Firmino's goal helped Brazil extend their winning run to eight matches at the expense of South American rivals Chile at Arsenal's Emirates Stadium.

Hoffenheim striker Firmino latched on to Danilo's pass and took the ball around Chile goalkeeper Claudio Bravo.

It was the highlight of a low-quality match punctuated by fouls.

Chile's Gary Medel was lucky to escape unpunished for treading on Barcelona striker Neymar in the first half.

With the Copa America starting in Chile on 11 June, it was the last chance for the players to impress before the squads are announced on 1 June but enthusiasm appeared to be lacking.

Neymar's free-kick from deep was close to sneaking in at the far post and Bravo was forced to push the ball wide for a corner before Douglas Costa missed Brazil's best chance of the half.

Brazil have won all their matches since the 2014 World Cup

Marcelo's cross from the left found the Shakhtar Donetsk midfielder but he fired wildly over the bar from 10 yards.

The setting was familiar for Arsenal striker Alexis Sanchez and the striker had Chile's first meaningful attempt on goal in the 65th minute when he curled a free-kick over the bar from 20 yards.

Brazil boss Dunga has enjoyed victory in every match of his second spell in charge since taking over after the 2014 World Cup.

That record looked in jeopardy until a fine pass from Danilo released Firmino. The striker was too quick for Medel and calmly took the ball around Bravo to score.

It was harsh on Chile, who have now suffered three defeats in their last four internationals.

Neymar came close to doubling Brazil's advantage when he whipped a free-kick narrowly wide in stoppage-time.
