 The London team had to pull out of the league shortly after as construction delays meant their arena would not be ready until May 1975.To bring the number of teams to an even number it was then decided that the team from Barcelona, the Catalan Estels, and the Madrid Superstars would be merged for the first season before playing separately the following season.Their respective owners - Sid Franklin and Carlos Pardo for Barcelona, Alan Becker and Enrique Godoy for Madrid - met and agreed to base the team in Barcelona but also play games in Madrid and elsewhere in Spain.
