The Nigeria international trained separately from the rest of the team on Monday morning due to a muscle issue and it poses a source of concern for Napoli, who open their Champions League group stage games against last season’s beaten finalists.
The Azzurri trained at Castel Volturno on Monday morning following their 2-1 win over Maurizio Sarri’s Lazio on Saturday.
Napoli are currently top of the Serie A table along with Milan, but could see their star striker Osimhen not only miss the upcoming European clash, but also Saturday’s Serie A fixture against Spezia.
