Andrea Della Valle admits they could sell up at Fiorentina.
The businessman owns the club along with brother Diego, but failure to qualify for Europe for two consecutive campaigns prompted protests from the supporters.
"If a part of the city does not want the Della Valle family to carry on with this club, then they should tell us that clearly. I won't stay where I'm not wanted," slammed Della Valle in the Corriere dello Sport.
"Our objectives have not changed. We want to battle for a finish behind the top four. A place in the Champions League won't be easy, but we want to qualify for the Europa League and the Coppa Italia.
"I am considering whether to write down a pact with the city so there are no more misunderstandings over our targets. If that's not accepted, then we'd immediately ask around if there are people who can do better for Fiorentina."
