Chelsea boss Roberto di Matteo is coy over their pursuit of Internacional midfielder Oscar.
The Blues are understood to be close to an agreement for the Brazil international.
Di Matteo said: "I can tell you that he's not a Chelsea player so it's difficult for me to talk about a player that doesn't belong to us.
"I know there has been speculation we are interested in this player and in due course if there is anything to announce we will do. All I would say is that he is a very young talented midfield player."
