The Brazilian feels he made the right choice in moving to Stamford Bridge, and is pleased with the way he has taken to life in London despite having many offers in the summer
The Brazilian midfielder was one of the most coveted young players in world football this summer, and opted to move to west London under then manager Roberto Di Matteo.
The 21-year-old has made a fine start to his Chelsea career, scoring a scorching effort on his Champions League debut against Juventus and, despite the language barrier, Oscar is delighted at the way he has adapted to life in London.
“There’s a realy good atmosphere at the club,” he told Fifa.com.
“I get along great with everybody, but I’m still getting to grips with the language, so I obviously spend more time with the Brazilians. We get on really well, we’re always having a laugh.
“There’s obviously a process of adaptation, but I’m very pleased with how I’ve settled in. I feel very comfortable playing in this system and I have developed a good understanding with my team-mates.”
Eden Hazard joined alongside Oscar this summer at Stamford Bridge, and the pair – alongside Juan Mata - have been attracting headlines for their eye-catching performances so far this campaign.
“They’re both superb players, among the best in the Premier League,” the Brazilian continued.
“It’s always easier to play with players who are not only great but also intelligent. I think we link up well and that our styles complement each other. I think we give the supporters a good deal of entertainment.
“Chelsea have adapted to my style. Last season they played a different way, but with me and Eden coming in to join Juan, I think they’ve modified the way they play and become more attacking. We get the ball down and knock it about more now, which, being Brazilian, I really enjoy.”
The 21-year-old is expecting a tough fight for the Premier League title from the Manchester clubs, but insists that Chelsea have the ability to top the table, as well as finding success in Europe and the Club World Cup.
Oscar said: “[Manchester] City have a lot of excellent players and are the reigning champions, and they’ve become very adept at grinding out results. But Manchester United have been there and done it time and time again. They’re both excellent teams.
“However, I’m confident Chelsea will do it. We’ve got a different team to last season, so we’re in a transitional period. I think as the season goes on, we’ll get more used to playing together and play better as a result.
“Barcelona took it [Club World Cup] very seriously last year and we’ll do the same.
"I know Corinthians well and they’re a very strong side, well organised. They will be desperate to win the World Cup – it’s so important in South America. But we’ll be fully prepared for all our opponents.”
