Athletic Bilbao announced on July 5, 2026 the appointment of Edin Terzic as head coach. In his presentation, the German said: "I want to feel San Mamés and its passion," and explained that, despite offers from other clubs, he instantly knew his future lay at Lezama.

Terzic stated he has not requested signings because he fully trusts the rojiblanco academy. "The solutions are in Lezama," he asserted, emphasizing the importance of the youth players. He also recalled a conversation with Jupp Heynckes, who encouraged him to follow the footsteps of coaches who already worked at San Mamés in the 1990s.

The new manager made clear that promoting academy talent will be the priority. In the same press conference, the club confirmed the loan of Ibai Sanz to Segunda División side Córdoba, after he scored twenty goals in the last two campaigns with the reserves. Terzic considered the move opens a spot for another youngster to rise to the first team.

Athletic Bilbao will open Lezama to the public on Thursday July 16, offering the first open‑door training after the season opener against Derio. Terzic will take part in the session, greeting supporters and strengthening his bond with the fans. The club also announced medical examinations for the 35 players under his charge, while awaiting the return of World Cup participants and the recovery of Egiluz.

Terzic admitted he would have loved to play in Europe this season, but his current goal is to bring Athletic back into the race for European spots. "We want to be part of Athletic's history," he said, adding that San Mamés' passion will drive the effort.

The German coach will work with a refreshed staff, including specialists in set‑piece routines and strength. Pablo Orbaiz and Toscana Viar have left the club, while new professionals, such as a fitness coach from the World Cup, join to boost the team's physical preparation.

The day of the presentation coincided with the death of Carmelo Cedrún, Athletic legend and goalkeeper of the 'Once Aldeanos'. The club organized memorial events and recalled his key role in winning the league and three cups, including the triumph over Real Madrid's Di Stéfano side in Chamartín. Fans pay tribute to the keeper who linked the old and modern eras of Athletic.
