The two top international teams in the world – Brazil and Argentina – will face off against one another in Melbourne on Friday.
The old rivals will meet for the first time since Brazil humiliated the Argentines 3-0 on their own soil.
Argentina is struggling in the CONMEBOL World Cup qualifying group, currently sitting outside the automatic qualification spots.
With stars like Lionel Messi, Paulo Dybala and Angel Di Maria in town, new boss Jorge Sampaoli will be looking to make a statement with a win over Selecao.
And Chelsea winger Willian says Brazil know the match will not be easy.
He said: "When Argentina and Brazil are on the field, they both have good players.
"We are qualified for the World Cup, (which is) a very important moment but we are going to play to win, we're going to do our best.
"Argentina is changing the coach and I think they have a good chance to come back as a winner and qualify for the World Cup.
"Even though Neymar is not here, when Brazil and Argentina play, it doesn't matter who is on the field its always going too be a good game."
