Ray Lewington has joined England's coaching staff on a full-time basis, signing a four-year deal.
The 55-year-old worked alongside Roy Hodgson during Euro 2012 but was set to return to his role as Fulham coach in time for the new season.
However, Lewington has now ended his long association with the west Londoners to take up a permanent role with the England team.
"I'm delighted to be joining Roy's England coaching staff permanently," Lewington said.
"I really enjoyed the experience at the Euros this summer and am looking forward to spending more time with the squad as we look to qualify for the World Cup in Brazil.
"I would like to thank everyone at Fulham Football Club for such a wonderful time since I joined as a player in 1980. I have been coach, manager and assistant manager during my time here and this is a very special club full of great people dedicated to taking it forward.
"Being offered a full-time position with England alongside Roy Hodgson is a fantastic opportunity for me and one that I simply couldn't turn down. I'm excited at the prospect of being part of a special group of players and backroom staff, who will do their very best to make the nation proud."
There had been reports that the FA would have to pay £1million for Lewington's services, although Press Association Sport understands the compensation fee is in fact around £150,000.
Speaking of the deal, FA chairman David Bernstein said: "The FA would like to thank Fulham for their cooperation in Ray's appointment to the England coaching set-up. I am personally very pleased to have Ray with us full-time as we look to build on the foundations laid at Euro 2012.
"We have important games coming up soon: the August fixture sees England facing Italy again before the World Cup Qualifiers start in earnest with Moldova and Ukraine during September then San Marino and Poland in October. Ray will be playing a key role as we approach these matches."
