Under La Liga regulations, Barcelona are allowed to sign and register a replacement player if the injured footballer is expected to be out for four months or more. This forecast must be supported by a medical report approved by the competition's Medical Commission. Barcelona have up to 20 days to request the registration of a replacement once the Medical Commission issues a favourable report, and they can use up to 80% of the injured player's salary.
Andreas Christensen's injury has opened a regulatory window that allows Barcelona to temporarily use part of the defender's wages to register a replacement. However, turning that possibility into a completed signing will depend entirely on meeting a strict set of deadlines. As reported before, La Liga regulations allow clubs to use up to 80% of an injured player's salary to register a replacement, but this figure is adjusted depending on when the request is submitted during the season.
