I can sort of see why we didn't take on Cox, probably wanted to be first choice, and he would probably warrant that seeing him play. As a club at the moment, we probably can't afford a strong second string, as wage demands would be too high, and if we have cover with Greaves/Fleming/Coyle at present we just have to accept that.
On Tetteh, if we can get a good fee for him, and he frees up wages, which he was probably one of the high earners, and if we do get Connolly in one loan, then we are not in a bad position IMO.
