Napoli need to beat Arsenal at the Stadio San Paolo on Wednesday evening to have a chance of Champions League progress but they may have to do without Valon Behrami.
Slovakian playmaker Marek Hamsik is struggling with a foot problem and is currently training with special insoles to try and lessen the impact while running.
Hamsik would be a major loss to Napoli, who go into the game knowing the even a victory over Arsenal may not be enough if Borussia Dortmund beat Marseille as that would leave all three teams on 12 points.
Arsenal know that if they avoid a three-goal defeat at Napoli they will be safely through, which they will be confident of achieving.
And the Gunners have received another potential boost with the news that Napoli may be without Swiss midfielder Behrami for their final Champions League encounter.
According to today's La Gazzetta dello Sport, Behrami is also suffering with a foot injury and is a doubt to face Arsenal.
