1. Non-payment or late payment of remuneration by an employer does in principle constitute “just cause” for the termination of the contract. However, firstly, the amount paid late by the employer may not be “insubstantial” or completely secondary, and, secondly, the employee must have given a warning, i.e. he must have drawn the employer’s attention to the fact that his conduct is not in accordance with the contract. This is not the case when the player has not demonstrated that he made any complaints regarding late payment of his salaries nor how this affected his situation to a point where he could no longer be expected to remain in a contractual relationship with his club.
