I signed Gaven when FM06 first came out (ie without any patches) and he was absolutely ****. I got him on a free, played him on the wing and he only ever got above a 6 once. Kept him for 4 seasons but there was no noticable improvement, then sold him to Portsmouth for £1.2m coz no-one else was interested in him.
Dont know what hes like with any of the patches installed though
