Cameroon's Clement Atangana died while on trial at a Vietnamese club
A promising Cameroonian footballer has died after suffering a suspected heart attack in training on Friday.
Clement Atangana had only just begun a trial period with Vietnam Division one side, Military Zone 4.
On Sunday, a doctor at the military hospital said that Atangana probably died of a heart attack.
The 22-year-old collapsed just 12 minutes into a training session on only his second day with the team and was immediately rushed to hospital.
Team manager Vu Quang Bao has been reported as saying that he had been impressed with Atangana and had intended to offer him a contract.
Atangana had represented his country at under-23 level.
