Zidane’s four sons are reportedly among the players that have prompted FIFA’s sanction, which the former France midfielder finds equally baffling.
He added: “My kids were born here and have spent their whole lives here, so it is absurd they cannot play football.”
Barcelona received a similar ban in 2015 but strengthened their squad significantly while the case went through an appeals process.
Madrid opted against that course of action during a relatively quiet off-season window that closed at the end of August.
ZIdane insists he does not regret their inactivity and remains confident in the resources at his disposal.
