The Brazilian shot-stopper is currently away on international duty at the Confederations Cup.
His focus is locked on that competition at present, but speculation surrounding his next move continues to rage.
Cesar is expected to be among those allowed to leave Loftus Road on the back of QPR's relegation out of the Premier League.
He has already publicly aired his desire to compete in a top tier next term, wherever that may be, and the former Inter Milan keeper has refused to rule out a return to Serie A.
Cesar said: "I'm happy to hear about the Roma interest.
"But at the moment I don't want to talk about my future. I am only thinking about Brazil."
He added: "I'm happy at the moment. After everything that happened at Inter, my career has changed a lot.
"But I'm here at the moment and QPR will decide my future as well."
