Serie A legend Fabio Capello supports Francesco Calzona taking charge of Napoli.
Calzona, a former Napoli assistant coach, will also remain in charge of the Slovakian national team.
Capello told Radio Kiss Kiss: "The situation is difficult, but the luck is that Calzona already knows most of the players and the game system that (Luciano) Spalletti used.
"Playing against Barcelona, everyone will be very focused on overcoming this difficult obstacle. Barcelona have problems when they have to defend."
Capello continued: "If (Victor) Osimhen returns, Napoli has a better chance. Post-Scudetto? There is a general relaxation that leads you to perform not up to the level of what you could do. Napoli's objective is moving forward in the Champions League and will be Calzona's only objective, that of seeing last year's Napoli again."
