Former AC Milan fullback Gianluca Zambrotta can see Stephan El Shaarawy being sold.
Manchester City and Napoli ate keen on the young striker.
"I think Galliani said something obvious," Zambrotta told Il Mattino.
"No player can be considered as unavailable for transfer unless you are a club like Manchester City or Paris Saint-Germain.
"We are talking about an important player, one which the club believed in a lot last season, but if the right offer was made
"It seems to me that last summer neither Thiago Silva or Zlatan Ibrahimovic were on the transfer list, but when certain figures are offered then you have to sell."
