The demand for football tickets in European top-leagues has been subject of several studies within the last years e. g. in France, England and Germany. These papers focussed mainly on single matches and the significance of factors like uncertainty, performance of the clubs or date and time of a competition. In contrast this paper tries to build up a simple model to estimate the average number of visitors in the course of a whole season. Moreover the market entrance of a second club is considered. While in stage one an old-established club represents a regional monopolist, in stage two another club qualifies itself for playing in the first division what breaks up the old monopolistic position. Finally the model assumptions are compared to empirical findings from Germany and its major league.
