David Lopez will be suspended thanks to an accumulation of yellow cards, and Jonathan De Guzman is out with a minor injury that's held him out of training. With Gokhan Inler looking rather tired on Thursday against Wolfsburg, it should be surprising if we see Walter Gargano and Jorginho in midfield in this match.
Napoli are also still missing Camilo Zuniga, which will make it somewhat harder to give Christian Maggio a much-needed day off given that Giandomenico Mesto has been poor when he's played of late. Michu is also still missing, but it will be a shock if he ever plays for Napoli again.
The full 21 man matchday squad is listed below.
Goalkeepers: Rafael Cabral, Mariano Andujar, Roberto Colombo
Defenders: Christian Maggio, Giandomenico Mesto, Faouzi Ghoulam, Ivan Strinic, Raul Albiol, Kalidou Koulibaly, Miguel Britos, Henrique
Midfielders: Jorginho, Walter Gargano, Gokhan Inler, Dries Mertens, Marek Hamsik
Forwards: Manolo Gabbiadini, Lorenzo Insigne, Jose Callejon, Duvan Zapata, Gonzalo Higuain
