I may be guessing but I would imagine things like Ralstons performances against say Leverkusen and maybe Rangers may be important going forward, as in some of the bigger games I have noticed Celtic fans slate him for his ability in those games, which would have also been seen by Clarke and team, also I noticed Celtic are supposedly still in the market for full backs in January.
Ramsey to get in there barring injury a few good performances against the old firm or a move to the prem or elsewhere may be his way in.
Patterson has shown that he can get the job done already and in big games also, like some on here say are we also dropping Gilmour for not playing.
O'Donnell took his chances when we had no one, yes I agree again not the ability or form but could imaging him seeing out this season in the squad.
I think January may be key to some, if say Paterson or Ramsey move and including Ashby who I could see going on loan somewhere, Ralston depending who Celtic bring in.
