Gary Speed's sister Lesley has reportedly claimed that the former Wales manager showed no signs of depression leading up to his suicide in 2011.
The 42-year-old was found hanged at his family home in Cheshire by his wife on November 27 two years ago.
During BBC3 documentary Football's Suicide Secret, Lesley says, according to The Sun: "Trust probably had a lot to do with it. Who could he trust? What if it got out? He would be seen as weak. Depression wasn't really talked about in our family. It was something you didn't have.
"You get treated if you have an illness but with depression people tend to withdraw and you don't know. Maybe he thought he had to put on this persona and hide what he was feeling."
An inquest ruled a narrative verdict, claiming that there was not enough evidence to determine that Speed had committed suicide, indicating that his death could have been an accident.
