Dario Bonetti says he will be going to Fifa on Monday over what he says is a breach of contract by the Football Association of Zambia (Faz).
The Italian lost his job less than 48 hours after he qualified Zambia to next year’s Africa Cup of Nations finals.
He says Faz have not explained his dismissal to him and added he had a contract until July 2012.
Faz president Kalusha Bwalya called the BBC to explain a letter has been sent to Bonetti.
He however refused to comment further on the situation.
“As far as Faz is concerned this case is closed, we want to move on with our new coach Herve Renard,” he told BBC Sport.
