Cuadrado has been linked with the likes of Manchester United, Barcelona and Bayern Munich after impressing at the World Cup with Colombia.
Cuadrado was co-owned by Firorentina and Udinese before the Viola bought his full sporting rights earlier this summer and is under contract at the Artemio Franchi until 2017.
Prade insists they have had no official offers for Cuadrado and that they will talk with the 26-year-old about his future when he returns to Italy next month.
"We hope he remains with us", Prade told Sky Sport Italia. "We have never had official offers for him.
"We talk frequently with him and his agent. On August 4th or 5th he will be back in Italy and then, we will talk."
However, Prade refused to rule out a move for Cuadrado if the offer is right.
"It would be really difficult refusing a €50 millions euros offer."
"Let's wait, and let's see what will happen."
