Rangers showed they can still compete with the top sides in the country by dumping in-form Motherwell out of the Scottish Communities League Cup with a 2-0 victory at Ibrox on Wednesday night.
The Light Blues faced top-flight opposition for the first time since being consigned to liquidation and voted into the Irn-Bru Third Division in the summer when the Clydesdale Bank Scottish Premier League leaders came calling in the third round tie.
Motherwell were branded favourites by their hosts ahead of this game but any hopes of claiming a first win at Ibrox since 1997 were dashed by goals from Lee McCulloch and Dean Shiels as Rangers booked their place in the quarter-finals.
Aberdeen substitute Scott Vernon snatched a dramatic 93rd-minute winner against Dunfermline to send the Dons into the fourth round.
The tie appeared destined to be heading to extra-time but the marksman bundled in Niall McGinn's teasing delivery with seconds left.
The visitors had been booed off at the interval following a first half dominated by the First Division side.
But after some resolute defending and fine goalkeeping from Jamie Langfield, Aberdeen snatched the win after a more competitive display after the break.
