Interpreting registration rules
The quote raises the issue of no registration spots, potentially due to salary limits impacting license slots. It suggests the winter window won't sign unless a sale happens first. I should provide context about the implications on positions and alternatives like promoting from the B team or recalling loaned players. I can offer a brief squad or schedule without running any code. I'll summarize key takeaways, reasons, and impacts, noting the injury replacement rule in Spain about free agent signings, including exceptions for long-term injuries.Clarifying emergency signings
Actually, RFEF does allow emergency signings in Spain if a player suffers a long-term injury (over 5 months). Historically, LaLiga restricted transfers outside the window, only permitting replacements from within Spain — and not for goalkeepers. Wait, emergency signings can happen! However, LaLiga may have tightened rules recently. I’ll mention long-term injury exceptions and potential player outgoings like sales or loans to create roster slots. Plus, clubs can use B team players without registration, as long as they are under 23.
