Oscar arrived from Internacional during the summer but after impressing in his opening six months in London, the Brazilian playmaker has revealed that he is enjoying his time playing in the Premier League.
The 21-year-old told the club's official website: "I'm very happy and we are enjoying it more and more day by day, my wife and family.
"Everybody is happy here and we are getting to know London a little bit more. I take English classes and it is improving all the time, so in two or three months, I think I will speak more and I can already understand some. I'm very happy in spite of the cold!
"Also, I am adapting to playing in England and the Premier League all the time. I think I'm playing well and now I'm starting games more often, I feel like I'm doing well. I hope I can continue to do this as it helps my improvement, and I want to help Chelsea win games, competitions and titles."
Oscar has scored nine goals in 39 appearances for Chelsea this season.
