I think the issue is, is that we are a league one club. Any PROVEN / BIG NAME goal scorer is going to be much higher in demand in the championship / lower end of the premiership and will have much better options on the table that we can offer.
Proven goal scorers are pretty hard to come by, so when they do become available it's going to be difficult for us to complete, thats why its up to Nige to unearth a potential proven goal scorer (McNulty) or take a punt on someone such as Winall who is young and has done it for just one season so hardly proven.
Without wanting to sound bladey blade, looking what Nige managed to cobble together and achieve last season and also looking at his transfer dealings this season (not just who we have signed but the maguire situation, refusing to pay over the odds for COG etc), we are heading in very much the right direction and I have faith that come what may, on the 9th of August, we will be in the best position the club has been in for a long long time and will be satisfied that Nige has done all he can to build a team capable of winning this dire league.
