From what i've read from Ajax/Dutch football fans this guy is quite over-rated. Can't remember the exact details but basically they seem to think he never has any pressure on him and is given acres of space.
Never gonna get that here, we need someone a lá Modric/VdV who unlocks tight defences.
It sounds like his play kinda slacked off in the league somewhat last year, but I'm willing to bet that had a lot to do with being one of the hottest prospects in Europe at 20, being lined up by some of the biggest clubs, and those moves not working out delivering a big blow to his psyche. Whether he's a professional or not, that fuckin sucks on a 20 year old. He played fantastically well in the Champs League regardless, and absolutely wrecked City in Amsterdam in October.
