Barca coach Ernesto Valverde is adamant the Chile international is not for sale.
But Marotta says: "I wouldn't have imagined being first with Inter two years ago. I would have liked to set my career up differently, but that is the beauty of football.
“Vidal depends on many factors, he is an important player for us.
"The position of the Barcelona coach is at risk, if they change, I don't know what could happen."
