AC Milan midfielder Massimo Ambrosini will not decide his future until he gets a decision from the Italian club.
The 35-year-old's current contract with the Rossoneri runs out in June and he has yet to be offered a new deal.
Sion reportedly want to sign the veteran midfielder, but his agent Moreno Roggi has said that he knows "nothing" about the Swiss club's interest in the Italian.
"It's the first time that I've heard about that option," he told Calciomercato.it. "I really know nothing about it.
"However, when you consider Massimo's desire to continue playing at the highest levels, I don't think that rumour has a future.
"It's his intention to wait for Milan. And, like every year, the directors will wait until the end of the season to discuss contract renewals."
Ambrosini has been at Milan since 1995.
