Oscar: I am very happy at Chelsea
The 20-year-old, who represented the Seleção at the London Olympics, joined the Blues for £25 million earlier this summer.
Oscar has only managed a string of substitute appearances so far with midfielders such as Eden Hazard, Juan Mata, Ramires and Frank Lampard also at the club.
However, the Seleção international is keen to fight for his place in the team after Brazil’s upcoming friendlies.
He said: "Everyone is gradually seeing my quality and I'm getting there slowly.
"Everybody knows me after the London Olympics. They know that I can help Chelsea.
"Following the two friendly matches with the national team, I intend to do my best to help my team during the season."
The youngster says he has settled in well to life at his new club, largely due to the help of his fellow Brazilians.
"David Luiz has helped me a lot. We were already friends before and that has helped, as well as Ramires," he added. "[Lucas] Piazón is here and he is also Brazilian."
"I have enough Spanish and Portuguese to communicate so I was received very well by everyone."
Chelsea is Oscar's first club outside of his native country of Brazil, following spells at São Paulo and Internacional, but is very happy to be playing in England.
Oscar said: "I am very happy to be here at Chelsea as it is a big club that plays in the major world championships.
"Thank God I had a good debut and now I have to be patient to be able to make the starting lineup.
"I am adapting slowly and hopefully I will be as happy here as I was at Internacional."
