The group, which consists of Europe's top 18 clubs, agreed at their latest meeting to press soccer governing body FIFA for compensation for releasing their top players to play in World Cups.
It is believed that, should G-14 prove successful, any deal could be worth about £40million from the next World Cup in Germany in 2006.
In return for such a compensation deal, G-14 is promising to drop its opposition to FIFA's Confederations Cup tournament in France in June and the Club World Championships planned for 2005.
Manchester United chairman and G-14 vice-chairman Peter Kenyon commented: "We accept that the Confederations Cup, for example, is contracted and will happen as planned but we think there is a way we can work with FIFA.
"It's also inevitable, given the way the game is organised, that all these issues will be linked together."
Added G-14 co-president Michael van Praag of Ajax: "At the moment the only ones who do not benefit from the huge revenues of the World Cup finals are the clubs who provide the players.
"We take all the risks because we get the players back demotivated, tired and injured. We also have to pay their salaries and insurance while they are away playing for someone else for up to six weeks."
