Sabatini said: "Daniele's contract does worry me, though I think it can be resolved, as he strongly wants to stay here. It's only right he looks at the market rate and makes his requests.
"We are discussing it in a very constructive way. The club has thought of a fairly innovative type of contract. It would be a huge loss if he did leave, and Roma must be ready to accept that, but I don't think it will come to that.
"Many emissaries came to Rome, but the big money offer the media talked about never actually materialised. De Rossi has never been for sale."
