Fiorentina coach Vincenzo Montella says there's no reason for Federico Chiesa to leave.
New Viola owner Rocco Commisso insists Chiesa won't be sold for less than 100m.
And Montella is 'very pleased' that the Italo-American billionaire is keeping to his promise.
President Commisso has been clear on his future, both in private and in public, and I'm very pleased about that," he told Sky Sport Italia.
Federico's a good player who can still grow and will do so with us."
