Gary Ablett, the former Liverpool and Everton defender, has died at the age of 46 after a long battle against cancer.
Ablett, who also played for Birmingham City and Blackpool, and had a season as Stockport manager in 2009/10, lost his 16-month fight against non-Hodgkin's lymphoma on Sunday.
"On behalf of Gary Ablett's family the LMA (League Managers Association) has today confirmed that Gary passed away peacefully last night following a hard fought 16-month battle against non-Hodgkin's lymphoma," said an LMA statement.
"Respected throughout the game by players, coaches and managers alike Gary will be sadly missed. The LMA's thoughts and condolences are with Gary's wife Jacqueline and children."
Liverpool manager Kenny Dalglish, who handed Ablett his debut during his first stint as boss at Anfield, offered his condolences.
"It's a sad, sad day for his family and everyone connected with Liverpool Football Club," he told liverpoolfc.tv. "The most important thing just now is to pay our respects to Gary, his wife Jacqueline, the two boys and his wee girl.
"Obviously he had a long battle and I'm sure it was a lot of suffering and a lot of pain for him but the only thing you can say is at least he won't be suffering any longer. I gave Gary his debut and remember him scoring on his first start at Anfield against Nottingham Forest.
"He was a really good servant to the football club not only as a player, but also as reserve team coach. He served the club proudly and credibly. It's very sad for everybody."
