The 42- year-old, one of the most respected young managers in the game, was found hanged at his North Wales home this morning.
Speed enjoyed a glittering career as a player at Leeds, Everton, Newcastle and Bolton before moving into coaching with his national team.
He has been leading a renaissance of the Welsh national side in recent weeks, but his life has been tragically cut short by what police are treating as suicide.
A spokesman for Cheshire Police confirmed: "At 7.08am this morning, Sunday 27 November, police were informed of an incident at Aldford Road, Huntington. Officers went to the scene where a 42-year-old man was found dead. There are no suspicious circumstances surrounding the death and next of kin have been informed."
The spokesman added that the man was found hanged.
Speed was one the most popular players of his generation, the highlight of his playing career a league title with Leeds United in 1992.
