Spots are limited in Europe. And Europeans have no real incentive to develop foreign talent.
There is this weird notion you must have your majority of national team players in Europe to be a successful national team. In Japan’s 100 year plan they want majority of their players Europe; yet America, Australia, Korea and other nations have same mentality yet spots are limited. It’s short sighted plan and idea, as in the future without doubt Europe WILL impose a foreign quota and ensure their national players play in their league.
I like Japan and Mexico national football leagues. Develop and foster a indigenous football league with a healthy football culture. Who said you can’t create World Cup winning team in the MLS, J League, CSL and so on in the long run.
The best performing American national football team player has been Donovan and for Japan has been Endo. Both played in their national league respectively.
The better method than just running to Europe, is creating a proper football league with real community engagement, real healthy competition, creating players on the technical and physical of European football and creating world class players in your respective league.
