As I am a big Kalmar FF fan and have been following Rasmus for some time now I can add that the Dutch league is not good enough for Rasmus. I'd say Premier League or Spain is what he would aim for. I doubt Holland is even considered by Rasmus.
He is probably the biggest talent that has come out of Sweden since Zlatan Ibrahimovic. He might not be quickest on the pitch and will need more strength, but he is still young and he always somehow manages to create time for himself in almost any situation. He's got a fantastic right foot and a very long throw.
Looking at his development ever since he dominated the midfiled against FC Copenhagen in December 2005, he is a right bargain at £5 million. Even though he will receive a big share of the transfer sum, this guy will probably look more at which club suits him best and where he can grow even better.
If you haven't seen this already, some of the goals he has scored. His passing foot is even better.....http://www.youtube.com/watch?v=b9y8g4aZHF0
