Napoli have sacked manager Walter Mazzarri after just three months in charge and replaced him with Slovakia boss Francesco Calzona.
Reports in Italy say Calzona has signed a contract until the end of the season and will remain in charge of Slovakia.
Owner Aurelio de Laurentiis thanked Mazzarri for “having helped the team in a tricky period”.
Napoli host Barcelona in a Champions League last-16 first-leg tie on Wednesday.
Calzona was appointed Slovakia boss in August 2022 and helped the nation qualify for this summer’s European Championship in Germany.
The 55-year-old previously had spells as Napoli assistant under Maurizio Sarri and Luciano Spalletti.
