Greg Dyke, the new Football Association chairman, will issue on Wednesday a passionate call to arms for English football to unite behind the national team, amid deepening concern over the depth of the pool of homegrown talent from which Roy Hodgson has to pick.

In a major speech, Dyke plans to focus on the future and importance of the England teams and the various development sides. He is expected to set specific performance goals for both the senior side and the age-specific development sides. In the buildup to a crucial week for England's hopes of qualifying for the Brazil World Cup, a Guardian study of the make‑up of Premier League starting XIs on the opening day of the season found that the number of English players had sunk to an all-time low.

The Premier League has trumpeted its new £340m elite player performance plan, which overhauls the academy system, and the FA is banking on its £105m national football centre at St George's Park to improve the quality of coaching under the director of elite development, Dan Ashworth. But the abiding fear is that in the time it will take for those interventions to bear fruit, the supply line of talent will all but dry up if opportunities for young English players in the multinational Premier League are not more forthcoming.

However, it is understood Dyke, keen to avoid conflict with the Premier League, will largely concentrate on the FA's policies and call on football's governing body to "up its game".

The Premier League chief executive, Richard Scudamore, recently expressed his frustration that his competition got the blame for the failings of the national side, pointing out that England had won nothing since 1966. He said: "The whole thing seems to me that if England don't win something it is someone else's fault. I have never, in my 15 years with the Premier League, never said the Premier League's success, or lack of, is someone else's fault. You have to make it yourself."

Dyke, who canvassed the opinions of a wide range of figures in the game including players and managers, was appointed in July and has said he expects to be in the job for four years until he turns 70.

The FA recently appointed Gareth Southgate to succeed Stuart Pearce as manager of the Under-21s and Dyke has promised to look at the entire structure of the England setup.
