Said by whom is the main question I have. When I googled him, the only things I got were a bare-bones Wikipedia page (which basically just confirms he exists) and some stories saying we are interested in him, one of which, from the Yorkshire Post, says that he is a hot prospect, but doesn't back it up with any facts. Where are the usual scouting/opinion pieces that you normally find for young players who are highly regarded? Either this guy is the best kept secret in Europe, in which case we should snap him up as soon as possible, or he is only the best prospect in Sweden according to his own mind (or the mind of his agent.)
His Wiki page says that he is a midfielder, while the other stories all say he is a left winger.
Edit: Here is a short YouTube video of him playing at Swedish youth level. He has some ability, but he doesn't look any better than Nathan Thomas really:
