Premier League chief executive Richard Scudamore hopes the ratio of home-grown players in the top flight can move closer to 50% in the future, but refused to put a timescale on when that might be achieved.
Asked if the current statistics concerned him, Scudamore told BBC Radio Five Live's Sportsweek programme: "In a way they do which is why we have put such an emphasis on the Elite Player Performance Plan."
He added: "We are making huge strides under our director of youth Ged Roddy, with everybody at the Football Association and Football League on board with the development plan which is entirely designed to bring through more and better young players, coached in better environments by better coaches.
"That is not to decry anything that is going on at the moment, but we would like to see that balance reduced. We don't want it eliminated, we still want to attract the best foreign talent we can. They have graced our Premier League, but certainly we do want to see more home-grown talent.
"You can't get involved in numbers. I want that number increased and if it was back towards 50% that would be good, if it was higher I would only want it to be higher if the English talent was good enough.
"We're not going to set high targets on this, it depends on how the rest of the game develops. Say we're sat here in 10 years' time with 100% of players English home-grown because football economies in Russia, China and the rest of the world have developed where all of the world's best talent drains off to these places, it would be a false number."
Scudamore believes it is now looking "a little ambitious" to expect goal-line technology to be in place in the league by the start of next season.
"We're probably not going to get a final decision from FIFA until June or July I would imagine. The idea that we could then have it in place, fully tested and installed, for next season may be a little bit ambitious," he added.
"I still hold out a hope though (for next season) but certainly the season after. All the signs coming out from FIFA and from (president) Sepp Blatter personally is that he is encouraging it and wants it to happen."
