The Catalan club play their bitter rivals Real in La Liga on Sunday, with SPL champions Celtic visiting for their Champions League Group G clash later in the month.
Celtic fans travelling to the city for the game on October 23 are also set to be hampered by a planned strike among the city's metro workers, who are unhappy with their working conditions.
Barcelona are holding negotiations to try and avoid the striking, which would cause chaos on the two matchdays at the stadium, which has a capacity of almost 100,000.
According the Forbes rich list, Barca are the third-richest football club in the world with a estimated value of £816 million.
Star player Lionel Messi is the club's top earner. The reigning world player of the year is paid a salary of £13m a year.
