La Liga officially announced that April 12 will be a special day with a full classic theme, where all the clubs from the first and second divisions will participate in a unique initiative to celebrate the history of Spanish clubs.

The teams are set to wear their most famous classic old jerseys during the matches, in a move aimed at evoking historic moments from the past.

The classic theme will also extend to include television broadcast graphics, the official ball, and even the referees' uniforms, allowing fans to experience the atmosphere of football as it was in past years.

On the other hand, Real Madrid has decided not to participate in this initiative, without disclosing the official reasons behind this decision so far.

This event is expected to add a special atmosphere to the matches of that day, as fans will have the opportunity to watch the clubs in their historic jerseys in an exceptional experience within the Spanish stadiums.
