The Brazil international has made an instant impact since arriving in England from Internacional for £25 million in the summer, linking up brilliantly with fellow midfield creators Eden Hazard and Juan Mata.
On Wednesday he made headlines again with a sensational 45-yard strike against Shakhtar - his fourth goal in as many Champions League matches - and afterwards revealed he is loving life in west London.
“It’s a pleasure to play for a team which attacks like this," Oscar told the Daily Mirror. " I’m Brazilian, so of course I like playing this style of football a lot.

“This is my first experience in English football so naturally there is a process of adaptation as I get used to the different environment.
“But I’m pleased with everything so far. And every game I play I get more used to it, so I know I will keep getting better."
The Stamford Bridge faithful have been treated to some dazzling football this season courtesy of Oscar, Hazard and Mata, and the young Brazilian insists their burgeoning understanding will only improve with time.
“I feel my relationship with Juan and Eden is growing with every game we play together, as we get used to each other," he added.
“You can feel it improving with every game that passes and every time we play together it feels like we understand each other more. Hopefully there is more to come.”
Fernando Torres believes such improvement is crucial to Chelsea's chances of silverware this term, after Shakhtar were only seen off by a last-gasp Victor Moses header.
“I was happy with the result but we know we must do much better and that we have to improve," Torres told the Daily Mail.
“We have been creating problems for teams, pressing and creating chances from their mistakes, but not when we have the ball like we’re used to.
“When we needed to win, we did. We did it last season against Valencia, Napoli and Barcelona – also the final against Bayern Munich.
“Shakhtar was really the first big test of the season and we did it as well.
“Maybe we were a bit lucky but Chelsea has this special thing that no one can buy.
“We all know this kind of situation cannot happen again because, especially in the Champions League, at times like these you can be out.”
