After the Selecao marched to their eighth consecutive Chevrolet Brasil Global Tour victory, CBGT takes a look at the key talking points from the win over la Roja

Brazil marched on to yet another victory on Sunday when they defeated Chile in their final test before coach Dunga announces his squad for this year's Copa America.

The match was a tight affair, with few chances for either team, as the Selecao made a slow start before a flurry of second-half substitutions. In a feisty contest which saw a number of heavy challenges, Brazil struggled in the early stages but emerged thanks to a lone goal from Roberto Firmino that once again arrived from a trademark Dunga counter-attack.

Below, Chevrolet Brasil Global Tour looks at five talking points from the Emirates Stadium.

Second out of the blocks

Just as in Paris on Thursday, Brazil took a while to get going. With six changes to the starting line-up, their lack of cohesion was exposed by a dynamic, high-pressing Chile side. The Selecao created few opportunities, with Douglas Costa missing the best chance of the first half when he volleyed over the bar after collecting a deep cross from Marcelo.

A strong Chilean midfield sought to neutralise the threat of Neymar with strong, tight marking. Dunga said a stuttering first half was to be expected given the number of changes to the side, though he was happy with the way his team picked up the pace in the second period.

Understudies may remain just that

A new-look Brazil midfield of Souza, Fernandinho, Douglas Costa and Philippe Coutinho failed to command the game as well as Dunga's sides. A lack of understanding was to be expected from an unfamiliar group, though some would have hoped to make more of an impression on their coach. Coutinho has starred in the Premier League with Liverpool but struggled to make an impact from his starting position wide on the left, where he was deputising for the rested Oscar.

Sao Paulo's Souza made his presence felt but will also be slightly disappointed he didn't make more of an impression in his first start. Neymar was left slightly isolated during the first half, hoping to pounce on rare mistakes in the Chilean backline. While they had hoped for a better performance, those who came into the side did show promise and nobody ruled themselves out of selection for the upcoming Copa America. However, Willian, Oscar, Luiz Gustavo and Elias are all expected return to the starting XI.

Fixed striker blunts attack 

With Roberto Firmino rested after his exertions in Paris, Dunga once again experimented with a fixed centre-forward as Luiz Adriano led the attack. However, he failed to reproduce the form that saw him become the Champions League's top group-stage goalscorer for Shakhtar Donetsk this season. He was a late replacement for the injured Diego Tardelli in this month's squad and will have to continue to shine for his club side if he is to retain a place with the national team.

With what is fast becoming a trademark counter-attack - similar to that which brought Brazil so much success during Dunga's first spell in charge between 2006 and 2010 - the Selecao have repeatedly lacked fluidity on the break when operating with a more orthodox striker. Dunga said after the game on Sunday that it is important to have the option of a fixed central target, however, and Luiz Adriano remains in the frame for that role.

Roberto Firmino books his flight

Roberto Firmino has practically stamped passport for the trip to the Copa America in Chile. This week he has shown the mental strength to lead the front four, providing the movement that Diego Tardelli brought to the attack in recent matches.

He scored the winner against Austria in November to maintain Dunga's 100 per cent record and repeated the feat on Sunday. Collecting a smart through-ball from Danilo, his dart into space saw him round Claudio Bravo and roll in the only goal of the game.

Firmino is also able to operate deeper in an attacking midfield role and that versatility makes him all but assured of a place in the squad that will go in search of Brazil's ninth South American crown. He now faces a battle with Tardelli for the starting role in Chile.

Marcelo turns up heat on Filipe Luis

Both are left-backs but Marcelo and Filipe Luis are very different players. The former provides a bigger threat going forward but the latter's increased defensive solidity has made him a Dunga favourite. Filipe Luis showed in Paris that he can offer more to the attack when given the freedom to work the flank with Neymar, but Marcelo's controlled display against Chile may have convinced Dunga that he too can play with restraint in a flat back four.

As it stands, Filipe Luis remains Dunga's preferred option, but Marcelo is now pushing him all the way – particularly as the Chelsea defender finds regular first-team football slightly harder to come by following his switch from Atletico Madrid last summer.
