Manchester United boss Sir Alex Ferguson believes clubs should have "a proportion of home-based players" - but is sure Arsenal would not agree.
FIFA president Sepp Blatter has announced he will lobby for restrictions on the number of foreign players in each team and Ferguson has voiced his support.
"It's certainly not wrong that clubs should be seen to have a proportion of home-based players," said the Old Trafford manager.
"I totally agree (with Blatter) but it would be a problem for a club like Arsenal. That's why they'll protest the loudest.
"You want to protect your own, and there is nothing wrong with that. But, for the good of the game in England, it would be good to see more home-based players at the top clubs.
"United's critics would say 'It's all right for you, you already have English players in your side'. But I think if you asked a neutral, they would rather see more home-based players."
He added: "Under the present Treaty of Rome, you couldn't make it law. It would have to be an agreement between the clubs. But if it went to a vote, I think it would get through [even though] there would be opposition from clubs like Liverpool and Arsenal, who have strong Spanish and French connections.
"It would certainly be a contentious issue but I agree with the principle of it."
