its not ignorant at all. There are great dutch footballer and some of them won this trophy. But some players, who won it, wouldnt even be able to start for any EPL team at all. So in which world is this a sign of quality? I dont say that you are automatically shit, but that its irrelevant.
Again, I dont think we should buy any player who is only eventually slightly better than the likes of young. Yes he is versatile, but eventually not good enough to play any of those positions on a high level. I think he´ll fail dramatically as wing back because he wont be able to cope with the speed of the EPL. He´ll do okay in midfield, because he is a decent player in this area, but in this area we already have enough "decent players".
If van gaal thinks that he needs more quality on this postion, he should sign someone who has the ambition to be a starter for the next 4-5 years and if he just needs cover, he should use some of the deadwood. Blind is the deadwood of tomorrow.
