Deletion of William Karlsson

Comment: Unless someone can find multiple reliable sources covering him to meet .  It is possible that such sources exist, especially in Swedish, since he is a highly regarded junior player.  But unless someone is willing and able to show evidence that such sources actually exist, I have to !vote delete.  I would be happy to switch if evidence of significant coverage is shown
