Following his performances at the World Cup with Colombia, the winger has been linked with moves to both Manchester United and Barcelona.
However, speaking to La Nazione, Montella has insisted that he has not considered life without the 26-year-old in his squad.
"I have never thought of losing Juan. He's been here in the past, he is here now and he will be here in the future. I don't think about how his story might finish. A player like him can play in every position in midfield."
Cuadrado scored 15 goals in all competitions for La Viola last season.
