Rangers took another small step forward by overcoming Aberdeen. Now they must take a giant leap by conquering Celtic.
Victory over Jim Goodwin's side on Sunday - earned thanks to a Ryan Jack equaliser and Kemar Roofe's extra-time effort - has set up an Old Firm showdown at Hampden.
It will be the most significant test of the progress that Rangers are making under new boss Michael Beale. Indeed, it will be the biggest occasion of the Englishman's career as he bids for silverware for the first time as a manager.
