We need to raise money and cut costs, not increase them. There's no chance we can put him on bigger wages than he's already on. None of us WANT to sell him, but unfortunately it's the financial reality of being in the Championship, you have to sell your best players eventually.
It's all very well saying sell someone else instead, but that requires clubs to actually make offers for those other players. At the moment, it appears THB is the only one attracting actual firm bids. If our asking price is met, he will almost certainly be off.
