Key questions facing Rangers before derby quarter-final

You could be forgiven for thinking you were watching two different Rangers teams in the first and second halves at Ibrox last Sunday against Celtic. In a blistering opening 45 they scored two goals, including an outstanding bicycle kick from Youssef Chermiti, had seven shots (two on target), and created three big chances.
