Regarding Ødegaard; Real Madrid and most other big clubs in Europe have been in talks with him and his father since summer.
It seems like Martin and his father spent a long time considering where to go. Has money affected the decision? Of course. But I highly doubt it's the main reason. I quite confident Real showed Martin and his dad that they believe in him and wants him to be a part of the next generation. (I think read somewhere in the Norwegian media, that his salary was exaggerated in British/Spanish media).
I've actually (unlike most of you) seen him play regularly for Strømsgodset and I am not talent scout but the talent is there

add to that, that his mentality is being praised. The kid is down to earth and his father does everything he can to keep him there. Very Scandinavian in that sense.
Oh, and training with Ronaldo, Bale, James, Modric, Isco, Benzema, Kroos and so on everyday
