Oscar admits having fellow Brazilians David Luiz and Ramires around him at Chelsea helped him to settle quickly in English football.
"It was very important for me to have them here and my adaption has been quicker thanks to them being here," the 21 year old told Globo Esporte.
"They have helped me a lot and we are good friends off the pitch. We have a good relationship and I'm sure that will continue throughout our careers."
Oscar is looking forward to turning out at Stamford Bridge when Brazil take in a friendly date with Russia on 25th March.
He added: "It will be very special to play with Brazil at Stamford Bridge.
"Playing with the national team is always special, but to do it here will be even more special. It's a unique occasion to play for my country at my club's home."
