Manager Manuel Pellegrini confirmed the news at his pre-match press conference on Friday. Adrián, 39, had already been expected to leave Real Betis at the end of the season, but his decision to retire entirely rather than seek a new club adds a definitive full stop to a career that stretched across more than two decades and two countries.
The announcement came through an open letter published on his social media accounts, addressed directly to the Betis supporters who have become his adopted family.
"In my career I have won titles, competed against great players and been team-mates with others who were even better. I have saved penalties, scored goals and been called up by my national team. I have achieved things that the little boy from Su Eminencia, whose parents took him to play on dirt pitches after working all week at the fruit shop, could never have dreamed of," he wrote.
He continued: "At Betis I have run like Rocky, had to negotiate with Don Manuel, saved and missed, been captain, tried to give my best on the pitch and on the bench, supported team-mates through injuries and difficult moments, spoken with the academy players who are our future, and played bangers like Free From Desire — which rang out in the Liverpool dressing room — to celebrate our moments of joy."
He then delivered the news directly: "You already know this will be my last match as Betis goalkeeper, but I want to announce that in the last few hours I have decided this will also be my last match as a football player. I am retiring in the place where I belong."
Adrián came through the Betis academy and broke into the first team in the 2012-13 season, making 32 appearances. The following summer he moved to West Ham United, where he spent six years and made 150 appearances before signing for Liverpool in 2019.
At Anfield he won seven trophies: the Premier League in 2019-20, the UEFA Super Cup that same year, the FIFA Club World Cup in 2020, the FA Cup in 2022, the EFL Cup in both 2022 and 2024, and the FA Community Shield in 2022-23.
He returned to Betis in 2024 and was part of the squad that secured Champions League qualification for the first time in over 20 years. His only appearance this season came in a league defeat to Atletico Madrid in February.
"I believe we achieved beautiful things," he wrote, "and above all I believe we have laid the groundwork for even more to come. So please: Real Betis must keep growing. Always have someone among you shouting what I ask for in every video: Keep going, keep going."
A career built on graft, loyalty and the kind of quiet durability that football rarely celebrates properly. He deserved the sendoff.
