From what I recall, we couldn't afford him when Thorn was still around as we looked at him then.
We've now subsequently taken him, but I'm sure Waggott stated at the fans forum that he's only here until January and we categorically can't afford him. The latter point being memory though, and I've slept recently so could very well be troubled with accurate recollection
Isn't he on his last year of his contract? Depends on what Forest are putting towards his wages and how much he would want next season if he is happy being at our club.
