Fiorentina president Andrea Della Valle says any player that doesn't believe in the Viola cause can leave this summer.
The Tuscans are out of Europe altogether next season.
"Anyone who doesn't care about the Viola jersey or feels they have completed their era here can leave," Della Valle told Radio Blu.
"We know that we already have a good squad and there won't be the need for any revolution. All we require are a few important signings to push into a solid group."
