Could well be Sheffield United that blocked the revealing of the transfer fee.
Fact is though, if we knew Baxter had gone for say, 500k, how much uproar would there be that nothing had been put into the playing budget from this (although it probably had, towards some wages)
There's obviously short-fallings and holes that have to be plugged at the club, hence the player sales. Maybe the financial situation is worse or better than we think? Who knows.
I'd wager that our club is more transparent than others when it comes to the wire. I do question why some fans think they have some innate right to know EVERYTHING about what happens in the club. Unfortunately, whilst paying good money to watch Latics, you don't gain access to the boardroom and all it's dealings for £300 and odd, maybe a bit more, a season.
What happens are board level, generally stays at board level, unless it is of vital importance to us fans.
