Rangers must continue picking up wins and hope Celtic drop points as they face a trip to Motherwell in the Scottish Premiership on Saturday.
A 3-0 win over Raith Rovers secured Rangers' spot in the Scottish Cup semi-finals in their last outing, and Michael Beale's side will face Celtic in the penultimate round as they look for their first trophy of the season. They won the competition last season under Giovanni van Bronckhorst and will be desperate to retain their crown. Rangers are yet to beat Celtic this season, with the Light Blues currently trailing the Hoops by nine points in the league, despite winning their last eight league games in a row.
Rangers are actually yet to lose in the league under Beale this season, but Celtic have been just as impressive in that time, with the nine-point gap yet to be touched. The Gers have faced Motherwell twice already this season, winning 3-0 at the Ibrox and 2-1 away.
