Napoli suffered their first defeat of the season in the Italian league, falling to Milan with a score of 2-1 last night at the San Siro stadium.

According to the website "Football Italia", Napoli is facing a significant crisis in their defense ahead of their anticipated match against Sporting Lisbon, scheduled for next Wednesday in the Champions League.

The source clarified that Dutch defender Sam Boeckema, the new recruit, is the only player guaranteed to participate, as the duo Alessandro Bonifazi and Amir Rrahmani are out due to injury, in addition to the suspension of captain Giovanni Di Lorenzo after his red card in the first round against Manchester City.

Luca Marianucci is also excluded from coach Antonio Conte's plans, as he is not registered in the Champions League list, while there are doubts about the readiness of the duo Leonardo Spinazzola and Matias Oliveira.

The report indicated that Spinazzola might play out of position on the right side if he recovers, while Miguel Gutierrez is likely to take the left-back position if Oliveira cannot return, and Juan Jesus may play alongside Boeckema in central defense.
