Man U and Them would be happy if there was no world cup
It's not that simple KND.....
This is a classic illustration of football being a business, and players being part property of their clubs and part property of their national football federations. Clubs recognize the benefit that they get from having international players, and they recognize the fact that major world tournaments present opportunities for marketing, scouting, exposure etc, so clubs would actually be
unhappy if there were no major competitions................
but they also recognize that they the club have significant leverage over their assets (players), because the federations don't pay players nearly anything close to their club salaries. In addition a club's leverage over a player is dictated in a detailed contract, whereas a federation's leverage over a player is more honor based (I've never seen a player-nat'l federation agreement..not sure if it exists, but I'm almost sure there are way less guiding covenants in it than a club contract)
........ultimately it's like they say, the more you have, the more you want. The clubs want a bigger piece of the pie, and they are trying to justify it........
The basic concept of finance- risk vs return. The higher the risk the bigger the expected return. Clubs see players going off on int'l duty as a risk....they want a bigger return....The final outcome will depend on which association has higher leverage and influence over the player... it varies from club to club, and from player to player.....and that's the problem, a standard ruling on such an issue cannot and will not please everyone.
