Oscar says he is expecting a real challenge when Brazil meet Chile in their World Cup round of 16 clash on June 28.

The Selecao booked their clash with la Roja with victories over Croatia and Cameroon either side of a goalless draw with Mexico, which saw them qualify as Group A winners.

Chile have impressed with victories over Australia and reigning world champions Spain and Oscar is well aware of the threat they pose to the World Cup hosts.

"At the World Cup, everyone has to face up and beat everyone,” he told Sportv.

“Chile are very strong opponent, but we'll be prepared.”

The Chelsea man also praised his side’s performance in their 4-1 victory over Cameroon in Brasilia on Monday night.

"It was especially good for us as a collective," he said.

"Everyone was trying to press and mark tightly in the other games, but it was not working.

"We could do it today. We pressed and intercepted some important balls. We got it at the right time."
