1. Any party wishing to prevail on a disputed issue, or wishing to draw legal consequences from factual circumstances it alleges, must discharge its respective burden of proof. This is, it must meet the onus to substantiate its allegations and to affirmatively prove the facts or circumstances on which it relies its argumentation on that issue.
2. There is the possibility to object to an amount of training compensation calculated on the basis of the indicative amounts mentioned in the FIFA Circular Letters and to prove that such compensation is disproportionate. This must be done on the basis of concrete evidentiary documents, such as invoices, costs of training centres, budgets etc. In case such evidence cannot be brought forward and in case the lack of proportionality cannot be proven, the general indicative amounts apply. In order to evaluate the training costs, and to evaluate whether the indicative amounts may be disproportionate, only economic factors, but not (subsequent) time factors such as an alleged short contractual relationship of a player with his new club may be taken into account.
