The only problem with signing Wharton from Blackburn, a contracted player with a Championship club, is that we would probably end up having to pay him more than Turnbull would ever have wanted! To me this would be a rather self -defeating result.
I suspect that another loan is the only viable option for us.
Ideal scenario for me (if, as seems likely, we are forced to sell) would be to sell Goode to Blackburn for 750K+ and then get Wharton back on a season-long loan as part of the deal. That way we would preserve that all important sense of continuity. I'm not at all keen on the prospect of starting the season with three new centre backs (and probably a new goalkeeper).
