I don't think the one uptop has to necessarily be a target man, 4-2-3-1 seems the standard formation for many teams these days and there are a range of different profiles for the centre forward. But from what I have seen of them Hamer, O'Hare, Rak-Sakyi are all exciting creative talents, but all carry a risk in terms of helping us retain possession ( this was an issue at the weekend). Moore if he plays to his best, gives us a great option, because he can hold onto the ball for us and allow the "3" to play off him, but he also still gets into good goalscoring positions. So in this sense, having another player who can win and hold the ball for us, as an option would be ideal. If we had the likes of Duffy, McGoldrick still in the attacking mid/winger positions, who were great in possession, then I think you can afford for the lone striker to be more of a Brewster or Campbell profile ( not that I have seen much of Campbell). Anyway tactics aside, both Brewster and Campbell come with a fitness warning, so we would ideally have another body in the pack.
