Yes I do agree with that (and have said as much) though there are always caveats. Godfrey is also a young player, and I'm not sure he is really the most worthwhile example I would think of in terms of holding a player back.
There's no doubt though, that we have been too short termist, and will probably continue to be with the current manager. In a big picture kind of way, I don't think we have really worked out what sort of football club we have to try to be.
I made a point a while back, that we could have easily promoted Ledson, Williams, Dowell and Kenny and got a similarish return to say Rooney, Klaassen, Sigurdsson (to a degree), Schneiderlin and Martina. We could have saved a tonne in wages, potentially more on fees, and had a much stronger identity.
There are going to be similar challenges with Nkounkou, Gordon & Brainthwaite I fear. And yes you can probably throw Kean in there too. I'd be delighted if Benitez just sort of said, if the appopriate bid doesn't come in, you're starting every week from now in, even if it means initially from the right hand side.
