There are only four points separating the two sides going into this Scudetto showdown.
Juve must do without Claudio Marchisio (who has flu), Mattia De Sciglio and Stefano Sturaro.
Max Allegri denied Dybala had a muscular problem, but reports from this morning’s training session claim La Joya had a large and visible strapping to his left thigh.
He is nonetheless expected to start in a 4-2-3-1 formation with Douglas Costa and Blaise Matuidi supporting Gonzalo Higuain, leaving Miralem Pjanic and Sami Khedira in midfield.
Benedikt Howedes and Kwadwo Asamoah are expected to be the full-backs, providing far more defensive cover than Stephan Lichtsteiner and Alex Sandro.
If it’s a 4-3-3 system, then Dybala could well be dropped in favour of Mario Mandzukic, returning Matuidi to his usual midfield role.
Napoli have everyone available except for long-term absentee Faouzi Ghoulam.
Maurizio Sarri is keeping his cards close to his chest, not testing out a line-up during this morning’s training session at the team hotel.
The issue remains between Arkadiusz Milik and Dries Mertens in attack, Piotr Zielinski and Marek Hamsik in midfield, or of course a 4-2-3-1 that would allow Jose Callejon, Mertens and Lorenzo Insigne to play behind Milik.
However, Sarri is reticent to change at the best of times, so it’s widely believed he will have the usual favoured XI in Turin.
Probable line-ups
Juventus: Buffon; Howedes, Benatia, Chiellini, Asamoah; Khedira, Pjanic; Douglas Costa, Dybala, Matuidi; Higuain
Napoli: Reina; Hysaj, Koulibaly, Albiol, Mario Rui; Hamsik, Jorginho, Allan; Callejon, Mertens, Insigne
