Can players change clubs in the same league after debut? What Spanish rules say | OneFootball

In Spanish professional football, making a debut does not bind a player to that club for the whole season. A footballer can move after an official match and, in certain cases, play again in the same competition.

Eligibility sits within RFEF and LaLiga rules for Primera and Segunda, and FIFA’s transfer regulations. According to AS, registrations are processed by LaLiga under the RFEF framework.

The key distinction is between registration and participation. Article 53.2 of the RFEF Competition Rules allows registration with up to three clubs in a season, but official matches for only two. FIFA’s rules mirror this.

A player may debut for club A, switch to club B and also play for B, even if both compete in the same league. The bar arrives with a third club, where playing is not permitted if he has already played for A and B. If he was registered with A and B but did not appear for one, he could play for the third side.

Umar Sadiq illustrated the point in 2025/26, starting at Real Sociedad and joining Valencia in January, both in the top flight. He also played in the same Copa del Rey edition for both clubs, which led Burgos to allege improper line-up. The RFEF dismissed the complaint, clarifying that FIFA’s article 5.5 does not impose an absolute ban on featuring for two clubs in one competition, the limit concerns more than two in a season.
