Napoli coach Maurizio Sarri said his side had faith in the security measures in place ahead of travelling to crisis-hit Belgium for Thursday's Europa League clash with Club Brugge.
The Belgian capital of Brussels was locked down for a second day Sunday with police and troops patrolling deserted streets as authorities mulled extending a security alert meant to prevent a repeat of the bloody Paris attacks.
The measures were imposed by Belgium's government over fears jihadists planned similar attacks to those in Paris which left 130 people dead on November 13.
Sarri, who saw his side go provisional top of Serie A on Sunday following a 2-0 win at Verona, said his side were "relaxed" about the prospect of travelling.
"If we're going, it means that the circumstances allow us to," Sarri told media in Verona on Sunday.
"Obviously, we'll be given police protection so I don't see what all the fuss about us going to play in Belgium is about. We're relaxed."
Napoli are already through to the knockout phase of the Europa League although a win for Club Brugge at the Jan Breydelstadion, located in Bruges, 100km from Brussels, would boost their hopes of snatching the second qualifying spot in Group D.
Napoli sit top of Serie A but level on points with Fiorentina, who occupy second place due to inferior goals difference.
Inter Milan will regain top spot with a win over Frosinone at the San Siro in Sunday's late game.
