PFA chief executive Gordon Taylor does not believe it will be possible for Fifa to enforce their controversial 'six-plus-five' plan.
Uefa are calling for a 'home-grown' player system to be introduced, meaning that clubs would have to include players who, regardless of age or nationality, have been trained by their club or by another club in the National Association for at least three years between the ages of 15 and 21.
Taylor believes that action needs to be taken to address the issue and to make sure that English youngsters get more of a chance, but he is in support of Uefa's plan rather than Fifa's.
"We are very much aware of the decreasing number of players qualified to play for England and it is one of the reasons why we have the embarrassment of not having England at Euro 2008," Taylor told Sky Sports News.
"But in Europe you cannot discriminate on the grounds of nationality so we have to really look at the Uefa proposal and say that not only should we have eight players in as squad of 25 that have been developed in a country or club irrespective of nationality, but to have them on the field of play.
"I'm not saying it should be eight but the figure should at least be four to encourage clubs to develop players for the next generation.
"That would put all clubs on a level playing field.
"It may well be that clubs look at bringing in youngsters from abroad , but it would at least focus them on developing players and at the moment they haven't got the patience to be doing that.
"We would be very much in favour of the Uefa criteria being developed further because the European Commission has indicated they would go ahead with that because focus is on youth development irrespective of nationality.
"That would give English opportunities at least the opportunities to succeed."
