Former Sheffield United defender George Baldock has died at the age of 31.
The England-born Greece international was found dead in the swimming pool of his house in Glyfada, southern Athens.
Baldock had joined Greek side Panathinaikos in the summer after seven years at the Blades.
Sheffield United expressed their shock at the news, saying: "The defender left the club in the summer after seven years at Bramall Lane and was extremely popular with supporters, staff and team-mates who pulled on a red and white shirt alongside him.
"The sincere condolences of everyone associated with Sheffield United are extended to George’s family and friends."
Baldock had made four appearances for Panathinaikos and started in their goalless draw with Olympiakos on Sunday.
The Greek Super League said: "The entire Super League football family expresses its deep sorrow for the untimely loss of Panathinaikos and our national team footballer, George Baldock, and extends its deepest condolences to his family and loved ones."
