They are mercenaries by the nature of business they are conducting. That's just fact. It has noting to do with their personal aspirations. These young players are being nurtured for 10+ years in some minor (and by 'minor' means not being among top10+whole EPL) clubs academy and as soon as they are ripe for picking, they are torn out from these clubs leaving them chump money so they can keep scouting and farming for bigwigs benefit. I think there should be some rules that would protect these small clubs from being at such disadvantageous position and could at least keep their core tad longer. Forcing big clubs some serious wage limit would also be good thing as in such case these youngsters couldn't be lured out of their home clubs by mere promise of blings.
I think something closer to how transfer market operated before Bosman rule would be preferable. I like the option for clubs to spice up their roster with some amount of foreign players, say, 4-6 legionaries on the whole squad. I think that's reasonable. It would protect smaller clubs making them more competitive and thus allowing them earn more and also creating more exciting tournaments. Many of you complain about these shit teams like Ferencvaros and Kiev, while at the same time supporting the system that makes them so shit. smh
I believe that one of the reasons why South American NTs have gotten worse in world cups is partly because of talent drain that has made their national leagues subpar. Their best talents get scooped off before they even mature and many of them fail in Europe and ruin their long term future, while not playing enough football and honing their skills in league that is less harsh for development. Notice how Spains NT was on its winning roll, when team consisted from 7-8 core Barca players and rest of them from Madrid. Players who had been playing together for years and had perfect chemistry. Same with Germany and Bayern connection. Italy in 2006 almost entirely from domestic clubs. France would be only exception. Still, Europe rules, because top nations suffer less from this unfair economic system.
