I'm sure that he would have a medical and what not but usually the fee would be agreed by then but he hasn't played football in 9 months or so. Bit risky to splash the cash as I don't think that we would be selling on the cheap either.
With regards to the holding him back, I don't think RDM would do that. It would be a bit like cutting off your nose to spite your face.... Surely he would want him fit as possible for pre season?
