Former RFEF President Luis Rubiales was detained in Madrid as part of a corruption probe.

The investigation centers on the Supercopa's move to Saudi Arabia, with accusations of corruption and money laundering.

Rubiales allegedly diverted €3.8 million to a construction firm for kickbacks.

He was released but is expected to testify soon.

Rubiales also faces a trial for alleged sexual assault during the Women's World Cup.

The RFEF is preparing for new leadership elections and pledges to cooperate with the investigation.

Rubiales denies the charges, but faces a possible significant prison sentence if convicted.
