At the conclusion of the current season, Óscar de Marcos will declare his retirement from professional football. During training at Lezama, the 35-year-old player informed his teammates of this development. De Marcos will say goodbye to Athletic Club, where he has earned his status as a legend by his exceptional on-field accomplishments and his admirable off-field behavior.

In the UEFA Europa League qualifying match against Young Boys at the Wankdorf Stadium, the Copa del Rey champion and two-time Supercopa winner, who will turn 36 in April, made his Lion debut. Athletic won 2-1 thanks to a goal from Iker Muniain, who has inherited the captain’s armband. On April 6 in Sevilla, the two were thrilled to hoist the prized cup title together. Furthermore, on Sunday in Cornellà, the model player from Laguardia tied Iker Muniain as the club’s second-all-time appearance maker with 560 games, trailing only José Ángel Iribar, who has 614 appearances.
