After years of injuries, surgeries, and repeated setbacks, former Atalanta, Juventus, and Milan defender Mattia Caldara has officially retired from professional football. In a heartfelt letter, Caldara opened up about the pain and frustration that ultimately led to his decision.

Caldara shared his farewell through a moving letter published on Gianluca Di Marzio’s website, offering a raw and unfiltered glimpse into his journey of struggle, resilience, and acceptance.

Football didn’t end abruptly for him; it slipped away gradually, through recurring injuries, operations, and relapses, until a medical verdict turned hope into an unavoidable reality.

“A blank page, a pen. I close my eyes, exhale. I open them again—now is the time. Dear football, I say goodbye. I’ve decided to stop. No, it wasn’t easy to make this choice. It’s not even easy to write these words. ‘Dear football, I say goodbye.’ I keep reading them over,” Caldara wrote.

“Maybe it’s a way to accept it. To accept it a little more. Now I’ve found some peace. But it took me a while to reach this decision. It all started in July after a visit to a specialist: ‘Mattia, you no longer have cartilage in your ankle. If you keep playing, in a few years we’ll have to fit you with a prosthesis.’ My body had betrayed me. This time, maybe for good.”

Caldara had reached the pinnacle of his potential just before his career took a downturn. At Atalanta, he established himself as one of Italy’s most promising centre-backs, earning moves to Juventus and then Milan—a trajectory that seemed destined for greatness. Yet fate had other plans, forcing him into a quiet spiral from which he could not recover.
