Firmino rounds keeper and slots home
Dunga has won all eight friendlies as Brazil boss
Second Chile defeat in four days
Chile host Copa America in June
Thanks for joining me this afternoon: Your texts, tweets and social media posts were much appreciated.
I'm going to throw you over to Tom Rostance, who is helming our live text commentary on today's Euro 2016 qualifiers. Northern Ireland, Scotland and the Republic of Ireland are all in action - so head over there now.
From me, it's goodbye.
There wasn't time to substitute Neymar in the end, by the way.
He wasn't at his best, and Brazil were certainly not at their most attractive. But Dunga has restored their self-respect after an awful end to their World Cup. They're in decent shape for the Copa America.
Chile play an energetic, high-temp game, but need to be better at creating chances with their possession.
Brazil secure an eighth successive win. It was scrappy, it was untidy, and I'm not entirely sure it was deserved. By substitute Roberto Firmino pressed his claims for a starting spot with a very nicely-taken second-half winner.
Image source, ReutersWe're well into three minutes of stoppage time. Neymar, trying to salvage an afternoon of personal frustration, wins a free-kick just as Dunga is preparing to substitute him. The Brazil forward stays on the pitch to take the free-kick - it wouldn't be fair to take him off at that point - and he whizzes a shot that bends away at the last moment.
Back to the action: Brazil's Robinho goes for a ridiculously spectacular volley from an impossible angle, and sends the ball squirting off in the wrong direction. Willian follows up by blasting a shot into row 13.
We've got a hold-up now, caused by a handful of pitch invaders. The stewards are on quickly to deal with it, though.
Where's the strangest place you've watched a match?
Charlie Bayliss: Tavistock Town v QPR for a pre-season friendly. Ended up something like 9-0. Not so friendly.
Alexander Dickens: Iraq international squad vs. England's National Game XI (semi pros) at Macclesfield's Moss Rose.

Brazil keeper Jefferson has been pretty much untroubled this afternoon, but he shows his concentration levels are still high by getting down to push aside Matias Fernandez's 25-yard free-kick. It looks as though the ball is bending just outside the post - but better to be safe than sorry.
Image source, PAIt hasn't been Neymar's day, but he's still trying. The Brazil forward runs into a phalanx of Chile defenders on the edge of the penalty area, and the ball pings out to Robinho, who volleys well wide.
Chile's Mark Gonzalez, who had a brief stint at Liverpool just under a decade ago, is on for Eugenio Mena.
Roberto Firmino has a chance for a second - and scuffs it. Willian and Danilo combine well down the right to find the Hoffenheim striker on the edge of the penalty area, but the finish is untidy and wide.
There's another Chile change, with Eduardo Vargas replacing Arturo Vidal - and so we now have two QPR loanees on the pitch.

What a strange game football is. Chile had all that possession, and didn't make any clear chances out of it. Now they are on course for a third defeat in four matches. This is not ideal preparation for the Copa America, which they will host in June.
Brazil have brought on Chelsea's left-back Filipe Luis in place of Marcelo. The Arsenal fans in the crowd at the Emirates Stadium respond with some hearty booing.
Image source, Getty ImagesBrazil have been second best today - but they're in front thanks to one of their substitutes. Danilo plays a pass through the centre of Chile's defence, and Hoffenheim's Roberto Firmino times the run perfectly to go round Claudio Bravo and score.
Chile respond by bringing on Matias Fernandez for Rodrigo Millar. Jorge Sampaoli's side have 17 minutes to deny Brazil an eighth straight win.

Image source, ReutersRoberto Firmino has a great chance to set-up a Brazil counter-attack - and wastes it by firing an over-hit pass that leaves Neymar sliding on to his backside as the ball whizzes out of play by the technical areas. Neymar, right now, may be wishing he'd phoned in sick today.
For all Chile's possession, they're being restricted to long-range efforts from free-kicks. Alexis Sanchez has another go from a good 30 yards this time, complete with fast bowler's run-up, but keeper Jefferson holds on.
Image source, APMiranda gets caught cold by Alexis Sanchez, who is motoring towards the penalty area when he is dragged back by the Brazil centre-half. Miranda is booked. Sanchez waves an imaginary card almost before he hits the ground. For goodness sake, man, it's a friendly.
Sanchez takes the free-kick himself, and lifts it over the bar.

Four substitutions at the Emirates for Brazil - and that means a return to an English football pitch for Robinho. The former Manchester City forward, currently playing for Santos, replaces Liverpool playmaker Philippe Coutinho, who did not an awful lot in his hour on the pitch.
Hoffenheim forward Roberto Firmino is on for Luiz Adriano, Elias has replaced Souza, and Willian has taken Douglas Costa's place.
The sun's out now. It's making me feel a lot cheerier.
Image source, APChile are on top in this game, at least in terms of possession, and they have a penalty shout rejected as Mauricio Isla darts into the penalty and goes to ground under Marcelo's challenge. There is, perhaps, a bit of arm-wrestling, but it's hard to tell who is the worst offender. Martin Atkinson refuses the Chilean appeals.
