Well, Rotherham seem to be doing their best not to pay for him, but they seem to like him - guess they are hanging on hoping he'll be theirs for free come next season. There doesn't seem to be a queue of prospective buyers.
Free transfer looks the likeliest bet.
Yes, that's a good shout, I think. If he goes out on loan and has a good season, we can get a fee for him; without the contract extension, he could have a good season and then someone could pick him up on a free.
