You need to think this one through a bit more Chesh.
A chance is a goal-scoring opportunity, which means that someone must be in a goal-scoring position, with the ball in close proximity. Presumably by this very definition, the player with the chance is in an attacking position. (Most unusual to have an effort from a defensive position). So that says very clearly to me that we have sufficient players in attack mode, with loads of opportunity. We really aren't lacking in players in forward positions.
Where we are lacking, and it's universally acknowledged, is that we're simply not converting these chances. Having more players in attack is not going to cure this particular problem. Utilising a different player or players might help, but if it was that easy ...
