Napoli are riding a wave of attacking confidence but facing a growing injury crisis that threatens to test their squad depth at the worst possible moment. The 4-1 win at Monza was a statement performance, with Rasmus Hojlund, Matteo Politano, Rafa Marin and Kevin De Bruyne all on the scoresheet, and it lifted the mood around a club that had drawn 3-3 with Roma the previous weekend. The problem is what it cost them. Stanislav Lobotka was carried off in tears on a stretcher in the 17th minute, and his absence now forces Allegri to reshape a midfield that was only just finding its best shape. Lobotka joins Benoit Badiashile and Leonardo Spinazzola on the injury list, both of whom were hurt in the Roma draw, leaving the defensive and midfield options stretched thin.

Scott McTominay has been the standout figure in recent weeks, scoring doubles against Bodo-Glimt and Roma, and his partnership with De Bruyne looks increasingly effective. That combination will need to carry even more responsibility against Juventus on Sunday.

Allegri himself will not be on the touchline. He accepted a two-match ban following his red card and post-match conduct against Roma, meaning assistant Marco Landucci takes charge at the Allianz Stadium. Napoli sit seventh, level on 14 points with Juventus in eighth, making this a direct confrontation between sides separated only by goal difference.
