The main point is that until this season we placed far too much emphasis on established players dropping down a level. Wilder has brought in a number of players from a higher level but crucially he's (mostly) bought players who have the potential to improve. Looking back since Simonsen skied that fateful penalty it's pretty clear to me that the transfer policy was, frankly, shite until this summer:
