Again, though, I suspect Robinson knows this. He has experience of both leagues and, as he mentioned in his interview, sees unfulfilled potential in Dunne he hopes to encourage.
In general, we can't afford players from exactly our level our above, so most of our signings are going to be lower league guys we hope to develop.
At the very least, maybe let's just give him a chance to show what he can do before moaning. Although I do realise there are a lot of posters who prefer the latter.
