I think he's had a fantastic start to the season. Oscar is essentially our Sergio Busquets (I'm not implying he's as good, because he's not) he recycles possession, moves the ball forward, linking the defence and the midfield while retaining possession, forming triangles for Hazard, Matic, Fabregas and Schurrle so that they don't lose possession and have an easy pass for when they're getting pressed hard. He's a key player for us.
