The pair are currently on Olympic duty for their country, where they have progressed to the semi-finals, and Santos star Neymar has impressed.
He has been linked with a move to Europe for several years, and Oscar has revealed he will be doing all he can to ensure when that move comes, he will be coming to Stamford Bridge.
"While we are in London, I have been telling Neymar about the ambition of Chelsea," he told The People.

Oscar joined Roberto Di Matteo's side for £25 million before the Olympic tournament began, and he admits that after hearing of the Blues’ interest he had little hesitation in deciding to move to England.
He added: "When my agent told me that Chelsea were interested it was not something I even needed to think about.
"They are the champions of Europe, but they are still showing so much ambition by improving the squad.
"To win the European Cup and still sign guys like myself and Eden Hazard shows you the ambition the owner and manager have.
"With the squad we have I will be looking at winning the Premier League title and also the Champions League.
"I know it is very difficult to win [the Champions League] twice in a row and even Barcelona could not do it, but with what Chelsea have in place it is very possible."
However before he gets his Chelsea career underway, the former Internacional man hopes to win Olympic gold for Brazil.
"The Brazilian Football Confederation have told us that they don't expect anything less than gold - and that is what we are going to deliver," he added.
"To win an Olympic gold would be very special for me."
