I'm not sure that is the case. I assume, without having seen him play admittedly, that he's a replacement in the "all rounder mould" for Gorrin. Someone who can defend but is also comfortable on the ball.
As for rebuilding its still early days and no need to panic. We all know where our deficiences lie i.e. wingers and strikers and Robbo has said this publicly. Without having seen him play I'm not sure Long is an out and out striker in the Number 9 mould. Scott, in my view, isn't quite ready yet and Johnson is a penalty box player. From Robbo's comments I suspect we'll play some variation of 4-5-1 this season which is great, but at the moment and for the next few weeks, we don't have the personnel to do it effectively. We certainly lack in the final third and need to acquire an out and out big striker an old fashioned number 9. I think we do look reasonably solid defensively, on paper, however. Anyone we bring in now might not be fully fit. Some good debate on Pie & Bovril about this. So it could be a harder league cup campaign in the group stages than we would wish. The saving grace is that the management team are well aware where we need to recruit and are actively working on it, albeit without much success so far. As we have nowher near replaced those who have departed, numbers wise, there will be money in the war chest.
