Transfer windows in sports, particularly in football (soccer), are specific periods during the year when clubs can buy, sell, or loan players. These windows are set by governing bodies such as FIFA and vary depending on the country or league. During the transfer window, clubs can negotiate deals with other clubs or players' agents to bring in new players or let go of existing ones. Once the window closes, clubs cannot trade players until the next transfer window opens. This system helps regulate player transfers and ensures fairness and transparency in the transfer market.
