1. The mere fact that there might be an existing contract between a player and a company on some personality rights of that player is not relevant and certainly does not make an employment contract concluded between that player and a club invalid or null and void. In international football sport, the concept of “federative rights” does not exist anymore and has been replaced by the notion – and value – of contractual stability. Therefore, contracts on personality rights between a player and a commercial company may have an “internal” validity and may have consequences in regard to the relations between the player and the company, but do not affect the power of such player to enter into an employment agreement with a football club and do not affect the validity of such employment contract even if the signing of the employment contract may be considered as a breach of the “internal obligation” between the player and the commercial company.
