Short of a twenty goal a season striker, a penalty box poacher, a midfield general, Something who can hold the ball and use it, a couple of maruading full backs and a blood and snotters Centre back?
In all honesty, we've got cover in every position, except full back, but even then, we've had that weakness from the start, and it wasn't deemed a priority. The only thing you could say is that none of our strikers are likely to score that many, yet trying to turn up a genuine quiality forward in the January window is a fairly hopeless task at the best of times - unless we end up bringing in a young player from the SPL reserves (which in turn will inspire all kinds of complaints about not giving our own youth a chance).
We don't necessarily need more players as such, though - arguably I'd say what we do need is to find a better balance in the midfield. You've got Scott and Callachan who are all action, dynamic headless chickens and you've got Moon and Fox, more measured, good positional sense, probably not quick enough as a unit. Somewhere in there is a pairing, or even a trio that will offer us the balance of covering pivot but able to support the forwards that the latter need to score more goals. nade and Stewart have proven before that if they get chances, they will score.
