Some of the problems identified are for example:

• The stands of the stadiums are often scenes of violent actions, also often penalized with fines to clubs. And these clubs can not prevent these violent groups from returning to the stadiums.
• The reselling systems and identifying entries make it easy to circumvent security systems spreading rapidly among the thousands of fans who also seek to enter the stadium.
• Some users may get uncontrolled high number of subscriptions that hinder access to new partners and are used for other commercial purposes outside the Club
