Oscar has heaped praise on Chelsea teammate Cesc Fabregas by insisting that the midfielder's influence is crucial to the team's impressive start to the season.
The Spain international controversially moved to Stamford Bridge in the summer from Barcelona following his eight-year spell with Arsenal.
Since his arrival, the 27-year-old has become an integral part of the Chelsea team and played a role in Oscar's goal during Saturday's 2-1 victory over Queens Park Rangers.
"Cesc helps the team so much and not just with the assists," Oscar told Chelsea TV. "In a game, he helps everyone, with beautiful passes like the one for me in this game.
"He has come in this year and played so well and I like playing together with him."
The Blues have a four-point lead at the top of the Premier League table following an unbeaten 10-match run.
