Barca president Josep Maria Bartomeu spoke in Cartagena, where Barcelona are playing a benefit match on Wednesday.
Asked about the team potentially being whistled because of the Catalan issue, he says he is "expecting a sporting and charitable atmosphere" for the game, remembering that Barca are here "to help and tell those hurt by the damage in September that we are with them."
Barca face Cartagena at 7pm in a match organised to raise funds for those affected by the torrential rain and floods that happened earlier this year.
Bartomeu added: "We're looking forward to collaborating and helping with a good game and offering a good spectacle that helps the people of Murcia."
