Lorenzo Insigne and Simone Verdi race against time to be fit for Napoli’s Champions League clash with Paris Saint-Germain.
It kicks off on Wednesday at 20.00 UK time (19.00 GMT).
The Partenopei are top of the group and still unbeaten on four points, followed by PSG and Liverpool on three.
Insigne was left out of the squad for last night’s 3-0 Serie A victory away to Udinese due to muscular fatigue.
It was not thought to be a serious issue following international duty, but the latest reports from Naples suggest he’s in a race against time to be ready.
Verdi was in the starting XI against Udinese, but lasted only three minutes before limping off with a muscular problem.
It’s believed he felt a twinge and decided with the medical staff to come off rather than risk making it worse.
