The Italy midfielder has been linked with a move away this season.
"He has two years still to run on his contract and, as far as we are concerned, he is not leaving," agent Dario Canovi told TMW. "His desire is to stay.
"Inter have yet to tell us of their intentions with regard to whether or not they want to renew his contract.
"He is happy at Inter and is ready to remain even until his present agreement runs out. The club just have to tell us what they want."
