As far as I can see, Arnautovic is by far the biggest talent on the dutch field. Only 19 years old, already 7 goals as a winger and very fast. Also very strong.
I can live with that list apart from the high Marcellis ranking and the Afellay inclusion. Much like most of his PSV team mates, Marcellis has been a bit crap this season. And Afellay is a seasoned international now, he's past the talent stage.
I wouldn't say he's by far the biggest talent but he is one of them players that you just know will end up at a very big club at some stage.
I realise that he hasn´t really had the time to make a real impact yet but Victor Elm of Herenveen is a huge talent (and for anyone interested his younger brother Rasmus is even better back in sweden)
