Barcelona's training ground was reportedly the scene of a fire this week ahead of the side's La Liga clash against Sevilla on Saturday.
The Spanish champions are believed to have suffered three blazes in as many weeks, causing concern over the safety of the players.
It is understood that the latest fire was put out near to the first-team changing rooms, but nobody was hurt by the flames, according to Catalan newspaper Ara.
Barca currently top the league table with a 100% record.
