Former FA chairman Greg Dyke believes that Brexit and a restriction on the number of foreign players coming into the Premier League could help the England team in years to come.
Dyke -- whose stated aim was to build a platform for England to win the World Cup in 2022 -- saw the national team eliminated from the 2014 World Cup at the group stage and knocked out of Euro 2016 by Iceland in the round of 16 during his tenure.
He believes one of the major problems facing England is the amount of experience home-grown players are getting in the Premier League, although that could be remedied quickly.
"Getting our young players real experience at the top level still remains, I believe, English football's biggest problem," Dyke said in a letter to FA staff that has been published by the Times. "Fewer home-grown players than ever started matches in the Premier League last year.
"Although I was not a supporter of Brexit, it could be that by leaving the EU this problem could be solved. If the FA and the government were to have the determination to restrict the flow of European players coming to play in Britain to the very best and introduce quotas on the number of British players in Premier League sides it could be changed quickly.
"At the moment many very average European players are increasingly taking the slots which could be going to talented young English players from clubs' academies."
Sam Allardyce is set to be appointed England manager on a two-year deal subject to the FA negotiating personal terms and a compensation package with Sunderland.
