Mariano Ondo Monsuy Angong (29 June 1999 – 14 September 2022) was an Equatoguinean footballer who played as a right back. He represented Equatorial Guinea at under-23 and senior levels.
Ondo has played club football for Cano Sport Academy and Shkupi.[4] [5] At the time of his death, he was expected to join Spanish club Rápido de Bouzas, after paperwork issues had been solved successfully - he had trained in that team during the 2021-22 season with a tourist visa, which prevented him from playing.[6]
Ondo made his international debut for Equatorial Guinea in 2017.
Ondo died whilst training with the Equatorial Guinea national team on 14 September 2022, at the age of 23.[7]
