There's no spark through the middle - either in midfield or up front. Shinnie and Ferguson are good players who give us a lot of energy, but neither of them are players who will unlock a defence. Forrester is useless - I don't like writing folk off so soon, but it seems obvious to everyone (including the manager) that he's not good enough. Up front we've got no creativity or goal threat.
The only time we've looked dangerous through the middle this season is the game when Wright played as no10. If we get him back fit and on form it could make a massive difference and would take a bit of pressure off McGinn and GMS who are having to carry the team as far as an attacking threat goes, and both of them being wingers are going to blow a bit hot and cold just by nature of the position they play.
