Delio Rossi is already fielding offers from rival Serie A clubs as his relationship with Lazio president Claudio Lotito reaches breaking point.
Controcampo says Lazio's defeat to Genoa on Sunday was the final straw for Lotito, who will replace Rossi for next season.
Napoli have already sounded out the Lazio coach about succeeding Edy Reja, while another unnamed Serie A rival have also been in contact with Rossi's representatives.
