Brady won't be sold for 5/6m in January - he'll only have six months left on his contract FFS!
Hull have put ludicrous price tags on three of their players, all of whom (supposedly) want to leave the club, but the interested parties have turned away. By all accounts, Hull barely have enough players for pre-season, so it makes sense that they don't want to sell for anything other than silly money. I'm sure their fans are delighted at this stance. But it's a dangerous game - they clearly aren't able to buy unless they sell (which if you look at our transfer policy was exactly the same for us last summer) and they are going to be left with three players who might be very good at Championship level, but might be difficult to motivate.
So you might applaud Hull for sticking by their guns, and their fans might be delighted, but it is an easy negotiation position to take - we won't sell unless the fee is £x gazillion, even if selling makes complete commercial sense, etc. That will be fine if they get promoted with those three players suitably motivated. That might happen. But the alternative is that those three players can't be arsed and their value evaporates and Hull are left with valueless expensive players and still in the Championship.
It might work. Our club chose not to follow that line when they sold Snodgrass and Fer, which I personally think was the right decision. IMO we won't be signing Brady for silly money, which is all Hull will accept, so we might as well forget about him and move on. Hull hold the aces, fair play to them, it's now their risk.
I don't know why people are panicking about signings though. Loads of time as danary says.
