I understand where you are coming from. It would be a huge, huge ask for the current Rangers team to go in against Celtic even although they would raise the game for the match.
Rangers' best performance of the season came on the day they deservedly defeated Motherwell in the League Cup although they weren't at the races against Caley Thistle in the next round.
I would fancy their chances against other SPL teams but Celtic at this moment in time would be a bridge too far.
