Well Stuart Armstrong seems to have picked up a good spell of form in a timely manner and Adams is knocking a few in. Despite the awful situation at present, assuming the game still goes ahead (no means certain) there are only a few places that might be available
Keeper - Marshall maybe getting his place back?
Defence - Replacement for Cooper if he doesn't return from injury
Midfield - one from McLean, Turnbull, Ferguson or Fraser (if he grovels to get back in)
Forwards - barring injury it should be Adams, Dykes, Christie and Brown
