Local police confirmed the death of 57-year-old Jose Becker, who had been swimming near his holiday home in the south of the country.
Becker had been swimming at a dam when the accident happened on Wednesday afternoon, Doroteo Machado Filho, a police inspector in the town of Lavras do Sul, told Reuters. No foul play was suspected.
Alisson joined Liverpool in 2018 from Roma and was voted FIFA Best Men’s Goalkeeper in 2019. His younger brother Muriel is a goalkeeper for Brazilian side Fluminense.
Internacional, who both brothers played for, tweeted their condolences.
“It is with great sadness that we received the news of Jose Agostinho Becker’s death, the father of our ex-goalkeepers Alisson and Muriel,” the club said.
Alisson played for Internacional between 2013 and 2016 before joining Roma, from where he eventually moved to Anfield.
