There's been reports about the condition of Theo Hernandez, physically, who has been suffering from fever. Today he continued to work seperately in the gym as he still suffered symptoms of flu.
According to Sky Sport Italia, another player is now suffering the fever: Alessio Romagnoli.
The Rossoneri captain, as reported by the Italian broadcaster, did not train today at Milanello. Therefore, Matteo Gabbia could be the centre-back to start from the beginning tomorrow against Napoli next to Fikayo Tomori.
