The Blues cruised into Sunday's showpiece event thanks to a comfortable 3-1 victory against Mexican side Monterrey.
Goals from Juan Mata, Fernando Torres and an unfortunate own goal from Darvin Chavez earned the UEFA Champions League holders an easy win.
But Brazilian star Oscar, who played his club football for Sao Paulo and Internacional before making his big money move to west London, is well aware of the danger Corinthians will pose on Sunday.
Speaking after the Monterrey game, the 21-year-old said: "I know Corinthians very well and they're tactically a very good side.
"Everybody knows they didn't play that well against Al-Ahly on Wednesday, but this is a final and they will be hard to beat.
"There will be no favourites in the final because both are great teams."
Fellow Brazilian Ramires was quick to mirror Oscar's comments and he also expects a tough final.
"Everybody knows Corinthians are a strong team and we know what an important title this is for them and their fans, but we are no different," he said. "It will be a tough game, like any final."
