Rangers boss Gio van Bronckhorst was left asking what more his side could do after giving champions in waiting Celtic a fright.
The 48-year-old was left cursing his side's luck in front of goal as they failed to capitalise on a dominant second half during the 1-1 draw.
But the stalemate leaves Rangers needing snookers in their bid to retain the title as they remain six points behind with three Premiership games left.
