Former Everton midfielder Andy King has died of a sudden heart attack, aged 58.
King had been working as MK Dons' chief scout and the club said: "The thoughts of everyone at MK Dons are with Andy's wife Barbara, his family and his friends at this extremely sad and difficult time."
King represented 13 different clubs as a player, but is best remembered for his two spells with Everton.
He also managed and served as a scout for several non-league clubs.
The statement added: "King, who joined the Dons' backroom staff in 2014, was a hugely respected figure throughout football and a magnificent individual and friend to many at MK Dons - he will be missed greatly."
King, who started his career with hometown club Luton, scored 49 goals in his six years at Goodison Park - between 1976 and 1980 and then 1982 and 1984 - including the iconic strike that settled the October 1978 Merseyside derby that etched his name into Everton folklore.
In their obituary, Everton described King as a "skilful, free-spirited, goalscoring midfielder, Andy King was - above all else - a crowd pleaser".
Before taking up the scouting job at MK Dons, King managed Waterford, Mansfield, Swindon, Grays Athletic and had a spell as caretaker manager of Northampton Town following Aidy Boothroyd's departure in late 2013.
