When planning how best to take the club forward would you not firstly sort out your coaching side before turning attention to the playing side? Now that the coaching side has been sorted I imagine that the playing side will be addressed pretty quickly as the transfer window closes at the end of the month.
I can't imagine any club having a complete squad overhaul in January so I imagine it will be strengthened by adding some players. Ray McKinnon said as much in his Sky interview. To help integration I hope every player is looked after.
