Nico Williams signs historic contract extension with Athletic Club until 2035
Nico Williams has reaffirmed his commitment to Athletic Club, signing a landmark contract extension that will keep him at San Mamés until June 30, 2035.
The new deal, announced today (July 15, 2025), by Athletic is the longest in the club’s first-team history and marks an eight-year extension on his previous contract.
The signing took place at San Mamés in the presence of club president Jon Uriarte, director of football Mikel González, his brother and club captain Iñaki Williams, and their mother, María Arthuer—who also serves as an ambassador for Athletic Club’s 125th anniversary. Friends of the forward surprised him with a personalized painting to mark the occasion.
Nico, one of the most promising international talents to emerge from the club’s academy, expressed his pride and excitement about continuing with the team he calls home.
“We have big ambitions ahead—like the Champions League—and what better place to chase them than with the club of my life?” he said. “I want to continue making history here at San Mamés, with our incredible fans and my family.”
The renewal comes at a pivotal time for Athletic Club, as they return to the UEFA Champions League for the first time in eleven seasons. Both Williams brothers are set to make their debuts in the competition, adding extra significance to Nico’s decision to stay.
Following in the footsteps of Iñaki, who signed a long-term extension in 2019 through 2028, Nico’s commitment is a major statement of intent. The club believes his continued presence sends a strong message about Athletic’s project and philosophy—choosing loyalty and identity over lucrative offers from abroad.
The event also celebrated the club’s WIN (Williams, Iñaki, and Nico) campaign, unveiling a new AC line jersey inspired by the brothers' shared journey. Nico was all smiles as he praised his older sibling:
“This is a dream we’ve always shared. Iñaki has always been my role model, and I think he’s the perfect captain. I look forward to seeing him wear the armband for many more years.”
Finally, Nico delivered a heartfelt message to Athletic fans: “I hope to give back everything they’ve given me. I’ve always felt immense love from the Athleticzale family. This renewal is for them too—I’m proud to have such incredible supporters.”
