1. A transfer cannot be qualified as temporary only because there is allegedly a unilateral option clause allowing, theoretically, the former Club to possibly extend its contract with the Player. In addition, the validity and enforceability of such an option clause is disputed under Swiss law. In other words, even if the former Club had exercised its option in a timely manner, the Player could have possibly contested the extension of the contract and thus his obligation to return to the former Club. This situation does hardly differ from a typical, final transfer of a player, who is joining a club after his former employer accepted the early termination of their contractual obligations against a financial compensation. Accordingly, the former club cannot derive any right from the alleged temporary nature of the particular transfer of the Player.
