Leonardi has said that Parma have a multi-year project which Donadoni is a part of and that the thought of him leaving the club is laughable.
"It makes me laugh," Leonardi told LegaSerieA.it. "For quite some time I am doing nothing else except denying those rumours.
"We made a multi-year project with him and everyone involved and who says such thinks is lacking respect, especially for the fans.
"We share the project also for the next year with the coach and I want to clarify that Donadoni is going nowhere."
Parma travel to Siena on Sunday in Serie A.
