Arsenal players and staff have been told to stay inside their hotel ahead of their crucial Champions League clash with Napoli on Wednesday evening due to safety fears.
According to The Mirror, Arsene Wenger's squad and backroom staff have been instructed not to leave their hotel without a security accompaniment due to the fear of violence from the Naples club's Ultra fans.
The Gunners know avoiding heavy defeat at the Stadio San Paolo will see them through to the knockout stages of the Champions League, but Wenger and his players have insisted they will be going to the Serie A side with the intention of putting on a similar performance to the away match with Borussia Dortmund.
However, the serious security fears ahead of the match could help to unsettle the Arsenal squad, as the report claims the squad have a tradition of going for a walk around the city they are playing in before Champions League away matches.
They will now have to find other plans as security advice has told of large groups of Napoli fans converging near the Premier League leaders' hotel.
Rafa Benitez's side were threatened with having to play this match behind closed doors after their Ultras sparked scenes of serious violence in their previous home tie against Marseille, which saw ten people injured and a spate of stabbings.
Travelling Arsenal fans have also been issued with security advice on how to stay safe as they make their way to the game.
