Rangers and Celtic rounded off a difficult week for both teams by playing out a dour 0-0 draw that will do little to ease the pressure on either Russell Martin or Brendan Rodgers. The Old Firm pair were each humiliated in the Champions League, Celtic beaten on penalties by Kairat as they exited the competition in the playoff round, with Rangers also failing to reach the league phase as a 6-0 loss to Club Brugge condemned them to a 9-1 aggregate defeat.
