Former Arsenal and West Brom full-back Don Howe has died, aged 80.
Howe won 23 caps for England and was in the backroom staff of managers Ron Greenwood, Sir Bobby Robson and Terry Venables.
He is also remembered for managing both the Gunners and the Baggies, as well as QPR and Turkish giants Galatasaray.
Football Association chairman Greg Dyke said: "It is terribly sad news and our thoughts are with Don's family at this time."
Howe was part of the Three Lions set-up for their two most successful tournaments in recent history, working with both Robson and Venables as they reached the semi-finals of the 1990 World Cup and the 1996 European Championship.
Dyke added: "He is widely regarded as being in the vanguard of coaching in England and I know that his loss will be keenly felt amongst the coaching fraternity in particular and not least by Roy Hodgson, who was close to Don.
"He was a fine player - named as one of West Bromwich Albion's finest - and, of course, he went on to play an integral part in Arsenal's history as a coach and later as manager.
"For his country, he not only appeared in a World Cup but he was instrumental in both Sir Bobby Robson's management team for Italia '90 and Euro '96 where he assisted Terry Venables.
"Even in his latter years I understand he continued to pass on his knowledge and advice to aspiring young coaches.
"It is a great loss for English football, especially following on so soon after the sad passing of Jimmy Hill."
