Fiorentina are expected to line up in a 4-3-3, with David de Gea in goal, protected by a back four likely including Radu Dragusin and Luca Ranieri. The midfield three of Fagioli, Oulai and Brescianini will look to supply the front trio, possibly featuring Mastantuono, Pellegrino and Njie. But that midfield lacks the physicality and experience to cope with Napoli's engine room. Vanoli's side will try to press high and use the width of the Franchi, but they are vulnerable to quick transitions. Their full-backs, likely Joao Mario and Valdepenas, will be asked to push forward, leaving space in behind.

Napoli, also in a 4-3-3, will be built around that formidable midfield. Lobotka sits deep, pulling the strings, while McTominay and Anguissa provide box-to-box energy and late runs into the area. Out wide, they have pace and trickery to exploit Fiorentina's advanced full-backs. The battle in the middle third is where this game will be won. If Napoli can bypass Fiorentina's initial press, they will find acres of space in the half-spaces. Expect Napoli to target the channels between Fiorentina's centre-backs and full-backs, especially on the counter. Set-pieces are another weapon: Fiorentina's zonal marking has been suspect, and Napoli have the height and delivery to capitalise.
