This is why all the hand-ringing and screaming at the sky that goes on in this forum regarding transfers is so painfully futile: we have no idea how we got to where we are, who we've tried for, why we have or haven't moved on. None at all.
We have no idea how effective or otherwise Thelwell is, or is being allowed to be by our S&P situation (which essentially amount to the same thing).
The only rational judgements we can make will be at the end of the window, and at the end of the season.
Fixed that for you mate - it's very simple...
