The Football Association has revealed plans for Premier League sides to produce more home-grown talent.
FA chairman Greg Dyke has warned that English football will have "nothing to do with English people" if there are no restrictions on non-EU players.
The organisation's commission has recommended that the minimum number of home-grown players in a club's first-team squad should be increased from eight to 12 - a change that will be phased over four years from 2016.
The FA also wants players to be with a club from the age of 15, instead of 18, to count as home-grown. It has also proposed that only the best non-EU players will be granted permission to play in England.
Dyke hopes that the plans will give young English players a chance while also reducing the number of "bog-standard" foreigners in the Premier League.
"We have to do this by negotiation with the different leagues and with the clubs - we have to convince them that this makes sense for English football," he told BBC Sport. "And we are helped by Harry Kane in truth - we are helped by seeing a young kid come into the Spurs team and become the top scorer in English football.
"How many other Harry Kanes are around in the youth teams of Premier League clubs? It was almost by chance that Tim Sherwood became manager at Tottenham for a time and put him in the side - otherwise he would still be out on loan at Millwall or somewhere else.
"If you apply the system we are just introducing over the last five years, a third of non-EU overseas players that have come here wouldn't get in. We don't want to stop the outstanding talent coming here, but there are an awful of bog-standard players as well.
"If we could get all this through, over the next three, four or five years, you could see the numbers of home-grown players going up from a percentage in the high 20s to 40%. It matters that this happens across the whole of English football, but it particularly matters to the top end of the Premier League."
The Premier League is understood to be sceptical of the proposals.
