Premier Sports Cup holders Celtic will visit Motherwell in the quarter-finals of the competition after the draw was made on Wednesday night.

Ange Postecoglou’s side ran out comfortable 4-1 winners over Ross County at the Global Energy Stadium in Dingwall to join Old Firm rivals Rangers in the hat for the last eight after their 3-1 victory over Queen of the South 24 hours earlier.

The Ibrox club have been handed a home tie against Championship side Dundee, while Partick Thistle’s reward for knocking out Arbroath is a trip to Pittodrie to face Aberdeen.

The Dons avoided a potential banana skin against League Two side Annan Athletic at Galabank, needing extra-time to secure a 4-1 success.

Kilmarnock produced a slight upset by defeating Hearts 1-0 at Tynecastle and they will now host Dundee United, who bounced back from a weekend nine-goal mauling by Celtic to defeat Livingston 2-1.
