Sunderland are understood to be willing to listen to offers for the man they signed from Paris St Germain for £6million in January 2011.
However, asked about the 29-year-old, Di Canio said only: "I don't want to talk about him.
"He is part of the squad and the club. He is here so we will see what is going on, but I have nothing to say about him in terms of a transfer."
