FA chairman David Bernstein says they let down West Ham United legend Bobby Moore.
Bernstein admitted more could have been done for the former England captain after he retired.
Writing in a column for the Sunday Times, 20 years to the day since Moore died from cancer, Bernstein said they should have utilised his expertise.
"Bobby was the man who led England to our ultimate moment of football glory. He remains an eternal credit to his family, friends and everyone involved with West Ham United," Bernstein wrote.
"I am aware the Football Association has been criticised over its treatment of Bobby once he retired from football.
"It saddened me that this is the case and while I am not privy to exactly what happened at the time, it is clear to me the organisation could have done more.
"If Bobby were alive today I am sure we would have asked him to be the chief ambassador for the Football Association in its 150th year.
"He was simply one of the nation's greatest ever footballers."
