Speed was only 42 years of age.
He played for Newcastle between 1998/2004 - making 275/8 appearances - scoring 39 goals.
Cost £5.5m from Everton, after he won a Championship winners medal at Leeds.
Good, strong midfielder who took his time to settle into the team, but gained a great understanding with Rob Lee.
He got most of his goals attacking from deep on corner-kicks, sneaking in unnoticed on the near post.
He joined Bolton in the summer of 2004.
Our thoughts go out to his family at this sad time.
