[eng] The world of sport, and more specifically football, has taken a lot of prominence
and relevance in the lives of people. Such is the importance that a business
phenomenon has exploded in this sector based on large investments to achieve a
worldwide advertising position. Sponsors are one of the sources of income for
football clubs, helping them to continue to grow and to undertake increasingly
ambitious projects. But sports sponsorship is not the only marketing tool that can use
a football entity, there are other factors that need to be taken into account that can
boost economic revenue. Some of these tools may have some barriers to entry, but
will explain how clubs elaborate and direct their marketing strategy according to their
faculties and obligations.
