Definition: Period when clubs can sign new players. Summer + January in most leagues.
Transfer windows limit when clubs can sign players. Summer (July-Aug in Europe) + January are standard. Outside windows, no transfers (loans of out-of-contract players sometimes possible). Transfer fees have escalated wildly: Neymar to PSG in 2017 (€222M) set the record. Free transfers (Bosman) save fees.
