Barcelona are set to lose $6.7 million by playing their Champions League match against Napoli behind closed doors.

Barcelona's next two La Liga matchdays will also be played without supporters.

"There is of course an economic loss. Not only for Barcelona, but for every club that has to play behind closed doors. It is everyone's problem and money is a secondary factor, health comes first. Barcelona will lose around six million euros. Obviously there is regret as it affects club members, fans and the world of football. We are in the middle of a unique situation," said club president Josep Maria Bartomeu.

Bartomeu also addressed rumors of paying an agency to monitor the club's social media activity. 

"Barcelona have not commissioned anyone to go against people. We did monitor social media to find out what was going on. We have to look at what is said about the club. Did I order something that criticises [others]? No. We did something to track [things]. It's 900,000 euros a year. We commissioned a study a few weeks ago to shed light on this. Barcelona have an obligation to keep looking at what's going on in the digital world. We look around the world; we have a brand that must be preserved. Our obligation is this. I spoke to the players and they told me to be calm. I am calm."
