How is he clearly not?
he is the most expensive that has come out of belgium, which i think is a better indication then the golden shoe (It's not difficult to guess the winner if you follow the media the weeks beforehand, which is manipulative in my opinion)
I also doubt that defour our witsel, or any other belgian, would do as good as fellaini is doing in the PL at this moment: playing every match, scoring 3 goals as a midfielder, quite important ones to.
