Chelsea's formidable mid-fielding duo could be competing against one another for a spot on the host nations side for the 2014 World Cup in Brazil next summer.
Brazil are spoilt for choice, but 22-year-old Oscar is hoping that national boss Luiz Felipe Scolari will make room for both players.
Oscar said: "There is a competition between Ramires and me but everyone is competing with each other.
"I and Ramires play together at club level and we are playing well. It will depend on the formation."
Both players are almost on a level pegging in terms of their goal ratio, with Oscar netting four goals in 10 appearances so far this season for Chelsea and 26-year-old Ramires producing three goals in the same amount of games.
And there could be another two boys in blue shirts playing for Brazilian side this World Cup, if Willian or David Luiz are picked.
This summer saw Willian make a £32million move from Russian club Anzhi Makhachkala to the London outfit, and since the 25-year-old has made a handful of appearances, netting one goal in last Sunday's 3-1 victory over Norwich City.
Willian worked his way up through Brazil's youth system, playing for the national side at Under-17, Under-18 and Under-20 levels.
He currently only has a handful of caps to his name - but all that is set to change over the next few days.
Luiz has made quite a name for himself, and is an established playmaker for the Brazilian national side.
He led Brazil to lift the Confederations Cup with a 3-0 demolition over Spain - current World and European champions.
