Why let that run out if they are still supposedly after him?
It could be until the end of June though, as the transfer window doesn't 'officially' open until July 1st.
Because then they can bid and we can turn it down. We haven't had much noise from Ince himself saying he wants to leave, nor have we heard SB say he's free to leave. People have assumed that because he had a good spell at Derby that's where he wants to be, but if we can persuade him to stay, the last thing we want is Derby popping up with the fixed price and nabbing him.
If, on the other hand, he has said he wants out then I assume we'll squeeze Derby for everything they have.
