Napoli's international break has brought little relief, with the injury situation at Castelvolturno growing more serious by the day. Mathias Olivera became the latest casualty after picking up a muscle problem in training with Uruguay, as reported by GOAL, adding to a list of absentees that is complicating Massimiliano Allegri's preparations significantly. Alessandro Buongiorno, who was expected to anchor the defence, has been sidelined since summer following menisco surgery and remains a long way from returning, according to GOAL. Scott McTominay's comeback is also at risk of being pushed back after his cardiac ablation procedure, with Il Mattino cited by GOAL suggesting he could miss both league and Champions League fixtures in the near term. Costantino Favasuli suffered a muscle injury on Under-21 duty, GOAL reports, while goalkeeper Alex Meret is only now working his way back to fitness after his Champions League injury against Arsenal. On the pitch, Napoli sit ninth in Serie A with seven points from five games, and the squad's limitations have been exposed. Rasmus Hojlund has struggled for club form despite scoring for Denmark, as noted by GOAL, while David Neres is only just returning to fitness after eight months out. One bright spot is Kevin De Bruyne, who impressed for Belgium against Turkey with a brace, giving Allegri genuine encouragement ahead of the home Serie A clash with Frosinone on October 10.
