The Super Lig leader was given permission to speak with the Netherlands international after they negotiated a fee with the Nerazzurri, and it was reported on Friday that the 28-year-old would "most likely" arrive at the Turk Telecom Arena within the next few days.
However, in quick response to the remarks made by the Turks' sporting director Abdurrahim Albayrak, Sneijder's representative insists he is unaware of an agreement between the two sides and is waiting on other teams to put their cards on the table.
"That's impossible," Lerby told Voetbal International. "We didn't even talk with Gala, so there couldn't be an agreement. I have no idea [about an agreement between the two sides]. Inter haven't told me about it. I don't expect Sneijder to sign a contract just yet.
"Anything is possible. Over the next few weeks we will consider every offer that comes our way. It's the choice of Wesley and his wife Yolanthe. Until then, Wesley needs to rest so he can make the right decision."
