Athletic has made Alejandro Rego's four-season contract extension official. MARCA had previously reported on June 11 that the agreement was close, except for variables which delayed the deal. The club had an option to automatically renew Rego for two seasons, but the parties negotiated a different, four-year agreement. The negotiations were delayed by economic conditions subject to variables.

He also mentioned that there is no urgency, as the club can unilaterally renew his contract for two more seasons. Rego expressed his desire to stay at the club for many years, emphasizing his attachment to Athletic.
