Oscar marked his full debut for
Oscar's previous outings for Chelsea had all come from the bench but given his
chance from the first whistle he shone on what was otherwise a
Chelsea manager Roberto di Matteo took the bold step of restructuring his ageing squad this summer and Oscar's signing was a key part of a process that the Italian hopes will placate sack-happy owner Roman Abramovich.
After the match Di Matteo said: "It was a great debut for Oscar. I thought it was the right game to start him and he did a perfect job tactically. He scored two goals and the second one was a wonderful goal.
"He is a big talent. He has got a bit of everything. We shouldn't forget that he is still a young man - he is only 21 - but he is already quite established in his national team already.
"I think we are very lucky to have him in our team."
The first of his brace was a long-range drive that picked up a fortunate deflection to speed past the despairing Juventus 'keeper Gianluigi Buffon but the second served as a more emphatic reminder of his undoubted class.
This curling effort, from just outside the 'D', was a gold-plated rocket that Buffon once again had no chance of saving.
Oscar (full name: Oscar dos Santos Emboaba Junior) signed for Chelsea this summer for a fee of around £22 million from Brazilian club Internacional, with the west London club reportedly fighting off the attentions of both Barcelona and Real Madrid to secure their man.
The 21-year-old has been playing professional football for the past four years after making his debut for São Paulo aged 17. There he proved that he is adept at striking the ball with the outside of his foot, can drift off players in an instant and has an eye for a long-range goal.
Oscar's strengths lie as a playmaker but during his time in Brazil he showed he also has the ability to play the role of goal poacher, which will cheer Chelsea fans pining for the firepower of the departed Didier Drogba - the previous incumbent of Oscar's No 11 shirt.
His reputation was forged as a club player but it did not take him long to make an impact on the international stage either, with Oscar becoming the first player to score a hat-trick in a U20 World Cup final as Brazil beat Portugal in 2011.
He also appeared for Brazil at the London 2012 Olympics, winning a silver medal in the process that provided him with what Chelsea hope will be a lasting appetite for London-based precious metals.
