Today's match is a home game for Arsenal forward Alexis Sanchez, who warmed up for the game by spending some quality time with his dogs, and posting a photo on Instagram. The one on the right has the leap of a top-class centre-back, by the looks of it.
Brazil XI: Jefferson, Danilo, Thiago Silva, Miranda, Marcelo, Souza, Fernandinho, Douglas Costa, Coutinho, Luiz Adriano, Neymar.
Chile XI: Bravo, Isla, Medel, Jara, Albornoz, Mena, Aranguiz, Millar; Vidal, Sanchez, Hernandez.
Chile have been inconsistent since bowing out of the World Cup to the hosts last June. Jorge Sampaoli's side were surprisingly beaten 2-0 by Iran in Austria on Thursday. Today's match at the Emirates Stadium is their last scheduled match before they host the Copa America in June. An improvement is required.
Dunga has remodelled Brazil since their World Cup humiliation. Strikers Jo and Fred have been moved out, as has goalkeeper Julio Cesar. Shakhtar Donetsk striker Luiz Adriano, the top scorer in this season's Champions League, has established himself in the attack. Atletico Madrid's Miranda has taken his chance in central defence. Botafogo's Jefferson is the new keeper.
Some players remain: Fernandinho, Ramires and Luiz Gustavo have been kept on. But the new-look Brazil look to be getting back to their best, beating France 3-1 in a Paris friendly on Thursday.
Luiz Felipe Scolari paid for that World Cup embarrassment with his job. For a new boss, Brazil turned to an old boss. Dunga was criticised heavily for Brazil's uninspiring displays at the 2010 World Cup. But since his return, they have picked up form, winning seven out of seven friendlies. Today they face Chile again - in north London.
Belo Horizonte, 8 July, 2014. Brazil are one win away from a World Cup final on home soil. They haven't lost a competitive international at home in 39 years. A nation expects. Standing in their way: Germany.
What followed was utter humiliation. A 7-1 defeat was Brazil's biggest at a World Cup. It was an embarrassment that shook a football-mad nation.
Belo Horizonte, 28 June, 2014. Brazil and Chile are locked in a nerve-shredding penalty shoot-out in the World Cup's round of 16. Chile defender Gonzalo Jara steps up to take the final kick. He has to score.
He hits the post.
Brazil go through. Bedlam.
