The club is reaping the rewards, and able to spend these sums of money, because of Wilder and Knill's previous excellence in the transfer market in building this team.
Some Blades might, understandably given that we haven't competed at this level in the transfer market before, feel a bit squeamish about the size of the fee. After all, we've seen other clubs - one of them not too far away from us - get carried away and overreach themselves.
The key point here, though, and the safety-net that allows us to pull off a coup like this, lies in the value of what has been assembled over recent years. Of course, there is always risk with any transfer but we can now show ambition at a level we've never seen before because we are a club that isn't saddled with huge debts and we have valuable assets littered through the squad.
Thus, if things took a turn for the worse and we had to pull our oars in, and even though we don't want to sell any of them, look at the value we have in our squad in Baldock, Stevens, O'Connell, Egan, Fleck amongst others. The centre-halves alone, would be likely to each attract fees above what we've just paid out on Berge.
The majority of the squad may have been assembled for relative peanuts but, having proved itself for 2/3rds of a Premier League season, it is a squad worth many tens of millions.
