Napoli’s Champions League match with Arsenal could be behind closed doors after the Marseille bus was attacked.
The Partenopei are on a warning from UEFA and a further sanction would see their next home game played without fans.
The club even released statements this week urging the ultras to behave impeccably  in order to avoid the risk of losing the crowd for what looks to be a decisive encounter for qualification.
However, reports are coming in that the Olympique Marseille team bus was pelted with rocks and even smashed a window.
Players managed to avoid injury from the broken glass, but this is a disastrous turn of events for Napoli.
