Overview
- Gayoso's death was confirmed by his son on Tuesday, May 26, 2026, in an emotional social‑media post that thanked treating doctors and hospital staff.
- He had been hospitalized at Sanatorio Trinidad Mitre with a serious pneumonia after publicly disclosing a diagnosis of amyotrophic lateral sclerosis (ELA) in 2024 and had stepped away from daily field work while remaining Boca's coordinator of goalkeepers.
- Boca Juniors held a minute of silence before training and issued an official farewell, while former players, including Sergio Romero, posted condolences and the club lowered flags at its training ground.
- Over nearly two decades Gayoso worked with clubs such as Vélez, Tigre, Racing and Nacional and became widely known at Boca for his detailed study of penalty takers, a method credited in reports with helping the team win 14 of 17 shootouts during his influence.
- His family faces compounded loss after the recent death of his wife, and Gayoso's analytical approach to goalkeeper preparation is expected to be honored in club memorials and tributes in the coming days.
